+New in 1.14:
+
+* C compilation, and the AC_PROG_CC and AM_PROG_CC_C_O macros:
+
+ - The 'compile' script is now unconditionally required for all packages
+ that perform C compilation (if you are using the '--add-missing'
+ option, automake will fetch that script for you, so you shouldn't
+ need any explicit adjustment). This new behaviour is needed to avoid
+ obscure errors when the 'subdir-objects' option is used, and the
+ compiler is an inferior one that doesn't grasp the combined use of
+ both the "-c -o" options; see discussion about automake bug#13378 for
+ more details:
+ <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378#35>
+ <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378#44>
+
+ - The next major Automake version (2.0) will unconditionally activate
+ the 'subdir-objects' option. In order to smooth out the transition,
+ we now give a warning (in the category 'unsupported') whenever a
+ source file is present in a subdirectory but the 'subdir-object' is
+ not enabled. For example, the following usage will trigger such a
+ warning:
+
+ bin_PROGRAMS = sub/foo
+ sub_foo_SOURCES = sub/main.c sub/bar.c
+
+ - Automake will automatically enhance the autoconf-provided macro
+ AC_PROG_CC to force it to check, at configure time, that the
+ C compiler supports the combined use of both the '-c' and '-o'
+ options. The result of this check is saved in the cache variable
+ 'am_cv_prog_cc_c_o', and said result can be overridden by
+ pre-defining that variable.
+
+ - The AM_PROG_CC_C_O macro can still be called, albeit that should no
+ longer be necessary. This macro is now just a thin wrapper around the
+ Automake-enhanced AC_PROG_CC. This means, among the other things,
+ that its behaviour is changed in three ways:
+
+ 1. It no longer invokes the Autoconf-provided AC_PROG_CC_C_O
+ macro behind the scenes.
+
+ 2. It caches the check result in the 'am_cv_prog_cc_c_o' variable,
+ and not in a 'ac_cv_prog_cc_*_c_o' variable whose exact name is
+ dynamically computed only at configure runtime (really!) from
+ the content of the '$CC' variable.
+
+ 3. It no longer automatically AC_DEFINE the C preprocessor
+ symbol 'NO_MINUS_C_MINUS_O'.
+
+* Texinfo support:
+
+ - Automake can now be instructed to place '.info' files generated from
+ Texinfo input in the builddir rather than in the srcdir; this is done
+ specifying the new automake option 'info-in-builddir'. This feature
+ was requested by the developers of GCC, GDB, GNU binutils and the GNU
+ bfd library. See the extensive discussion about automake bug#11034
+ for more details.
+
+ - For quite a long time, Automake has been implementing an undocumented
+ hack which ensured that '.info' files which appeared to be cleaned
+ (by being listed in the CLEANFILES or DISTCLEANFILES variables) were
+ built in the builddir rather than in the srcdir; this hack was
+ introduced to ensure better backward-compatibility with package
+ such as Texinfo, which do things like:
+
+ info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
+ DISTCLEANFILES = texinfo texinfo-* info*.info*
+ # Do not create info files for distribution.
+ dist-info:
+ @:
+
+ in order not to distribute generated '.info' files.
+
+ Now that we have the 'info-in-builddir' option that explicitly causes
+ generated '.info' files to be placed in the builddir, this hack should
+ be longer necessary, so we deprecate it with runtime warnings. It will
+ likely be removed altogether in Automake 2.0.
+
+* Relative directory in Makefile fragments:
+
+ - The special Automake-time substitutions '%reldir%' and '%canon_reldir%'
+ (and their short versions, '%D%' and '%C%' respectively) can now be used
+ in an included Makefile fragment. The former is substituted with the
+ relative directory of the included fragment (compared to the top-level
+ including Makefile), and the latter with the canonicalized version of
+ the same relative directory.
+
+ # in 'Makefile.am':
+ bin_PROGRAMS = # will be updated by included Makefile fragments
+ include src/Makefile.inc
+
+ # in 'src/Makefile.inc':
+ bin_PROGRAMS += %reldir%/foo
+ %canon_reldir%_foo_SOURCES = %reldir%/bar.c
+
+ This should be especially useful for packages using a non-recursive
+ build system.
+
+* Deprecated distribution formats:
+
+ - The 'shar' and 'compress' distribution formats are deprecated, and
+ scheduled for removal in Automake 2.0. Accordingly, the use of the
+ 'dist-shar' and 'dist-tarZ' will cause warnings at automake runtime
+ (in the 'obsolete' category), and the recipes of the Automake-generated
+ targets 'dist-shar' and 'dist-tarZ' will unconditionally display
+ (non-fatal) warnings at make runtime.
+
+* New configure runtime warnings about "rm -f" support:
+
+ - To simplify transition to Automake 2.0, the shell code expanded by
+ AM_INIT_AUTOMAKE now checks (at configure runtime) that the default
+ 'rm' program in PATH doesn't complain when called without any
+ non-option argument if the '-f' option is given (so that commands like
+ "rm -f" and "rm -rf" act as a no-op, instead of raising usage errors).
+ If this is not the case, the configure script is aborted, to call the
+ attention of the user on the issue, and invite him to fix his PATH.
+ The checked 'rm' behavior is very widespread in the wild, and will be
+ required by future POSIX versions:
+
+ <http://austingroupbugs.net/view.php?id=542>
+
+ The user can still force the configure process to complete even in the
+ presence of a broken 'rm' by defining the ACCEPT_INFERIOR_RM_PROGRAM
+ environment variable to "yes". And the generated Makefiles should
+ still work correctly even when such broken 'rm' is used. But note
+ that this will no longer be the case with Automake 2.0 though, so, if
+ you encounter the warning, please report it to us ASAP (and try to fix
+ your environment as well).

+The macro AM_PROG_MKDIR_P is no longer going to be removed from Automake.
+Let's see a bit of history to understand why.
+
+I had already scheduled the removal of the long-deprecated AM_PROG_MKDR_P
+macro (superseded by the Autoconf-provided one AC_PROG_MKDIR_P) for
+Automake 1.13 -- see commit 'v1.12-20-g8a1c64f'.
+
+Alas, it turned out the latest Gettext version at the time (0.18.1.1) was
+still using that macro:
+
+ <http://lists.gnu.org/archive/html/automake/2012-09/msg00010.html>
+
+And since the maintenance of Gettext was stalled, I couldn't get a fix
+committed and released in time for the appearance of Automake 1.13:
+
+ <http://lists.gnu.org/archive/html/bug-gettext/2012-04/msg00018.html>
+ <http://lists.gnu.org/archive/html/bug-gettext/2012-06/msg00012.html>
+ <http://lists.gnu.org/archive/html/bug-gettext/2012-10/msg00001.html>
+
+So, on strong advice by Jim Meyering, in commit 'v1.12.4-158-gdf23daf'
+I re-introduced AM_PROG_MKDIR_P in Automake (thanks to Jim for having
+convinced me to do so in time!)
+
+But then, Gettext (as said, the greatest "offender" in the use of
+AM_PROG_MKDIR_P), in its latest release 0.18.2, finally removed all the
+uses of that macro still present in its code base. Yay. So I thought
+we could finally and quite safely remove AM_PROG_MKDIR_P in Automake 1.14;
+and I proceeded to do so, see commit 'v1.13-30-gd01834b' and the merge
+commit 'v1.13-5-gb373ad9'. Well, it turned out I was wrong, again, and
+in a trickier and sublter way this time. Let's see the details.
+
+If a package's 'configure.ac' contains a call like:
+
+ AM_GNU_GETTEXT_VERSION([0.18])
+
+then the 'autopoint' script will bring the data files from the Gettext
+release *1.18* into the package's tree -- yes, even even if the developer
+has installed *and is using* Gettext 1.18.2! Now, these data files
+comprise m4 files (that will be seen by subsequent aclocal and autoconf
+calls), and of course, the pre-0.18.2 version of some of these files
+still contains occurrences of AM_PROG_MKDIR_P -- so Automake 1.13 errors
+out, and we lose. That already happened in practice:
+
+ <http://lists.gnu.org/archive/html/bug-grep/2013-01/msg00003.html>
+
+Moreover, while I might see it as not unreasonable to ask a developer
+using Automake 2.0 to also update Gettext to 1.18.2, that would not
+be enough; in order for gettext to use the correct data files, that
+developer would have to update his configure.ac to read:
+
+ AM_GNU_GETTEXT_VERSION([0.18.2])
+
+thus requiring *all* of his co-developers to install Gettext 1.18.2,
+even if they are still using, say, Automake 1.13 or 1.14. Bad.
+
+So I decided to re-instate this macro as a simple alias for AC_PROG_MKDIR_P
+(plus a non-fatal runtime warning in the 'obsolete' category), and drop
+any plan to remove it (see how much good those plans have done us so far).
+See commit v1.13.1-109-g030ecb4.
+
+Similarly, the obsolete '@mkdir_p@' substitution and '$(mkdir_p)' make
+variable are still supported, as simple aliases to '$(MKDIR_P)'.

+been doing that since Automake 1.12.4.
+
+We had scheduled to remove support for it altogether in Automake 1.13

+too would have started deprecating it by the time our 1.13 release was
+done. Alas, this hasn't been the case: the deprecation code is only
+present in the development version of autoconf so far (scheduled to
+become Autoconf 2.70). So ...
+
+
+For Automake 2.0
+----------------
+
+... we have decided to wait until 2.70 is out before really removing
+'configure.in' support. Since we plan to require Autoconf 2.70 in
+Automake 2.0 (so that we can remove the hacky code emulating
+AC_CONFIG_MACRO_DIRS for older autoconf versions), we are quite sure
+that Autoconf will actually have started deprecating 'configure.in'
+by the time Automake 2.0 is released.
+
+Note that the removal of 'configure.in' has already been implemented
+in our 'master' branch (from where the 2.0 release will be finally
+cut); see commits 'v1.13-17-gbff57c8' and 'v1.13-21-g7626e63'.

+Summary
+-------
+
+POSIX will say in a future version that calling "rm -f" with no argument
+is OK; and this sensible behaviour seem to be already very widespread in
+"the wild" (and possibly lacking only on those systems that are well on
+their way to obsolescence).
+
+Se we'd like to simplify several automake-generated "cleaning" rules
+accordingly, to get rid of the awful idiom:
+
+ test -z "$(VAR)" || rm -f $(VAR)
+
+See automake bug#10828.
+
+For Automake 1.14 (DONE)
+------------------------
+
+Add a temporary "probe check" in AM_INIT_AUTOMAKE that verifies that
+the no-args "rm -f" usage is supported on the system configure is
+being run on; complain loudly if this is not the case, and tell the
+user to report the situation to us.
+
+For Automake 2.0
+----------------
+
+Make any failure in the configure-time probe check introduced by the
+previous point fatal; and in case of failure, also suggest to the user
+to install an older version of GNU coreutils to work around the
+limitation of his system (this version should be old enough not to
+be bootstrapped with Automake 2.0, otherwise the user will face a
+bootstrapping catch-22).
+
+In all our recipes, start assuming "rm -f" with no argument is OK;
+simplify and de-uglify the recipes accordingly.
+
+For Automake 3.0

+
+Remove the runtime probe altogether.

+Summary
+-------
+
+We want to make the behaviour currently enabled by the 'subdir-objects'
+the default one, and in fact the *only* one, in Automake 2.0.
+See automake bug#13378: <http://debbugs.gnu.org/13378>.
+
+Details
+-------
+
+The fact that Automake-generated Makefiles place compiled object files in
+the current directory by default, also when the corresponding source file
+is in a subdirectory, is basically an historical accident, due to the fact
+that the 'subdir-objects' option had only been introduced in April 1999,
+starting with commit 'user-dep-gen-branchpoint-56-g88b5959', and never
+made the default (likely to avoid backwards-compatibility issues).
+
+Since I believe the behaviour enabled by the 'subdir-objects' is the most
+useful one, and in fact the *only* natural one, I'd like to make it the
+only one available, simplifying the Automake implementation and APIs a
+little in the process.
+
+Alas, since this also means changing the default behaviour of Automake
+('subdir-objects' is not enabled by default, sadly), this means the
+transition path will be less smooth than I'd like.

+The bug spotted by Nick Bowler:
+
+ <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378#35>
+ <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378#44>
+
+and exposed in test case 't/ccnoco4.sh' has been fixed (see commit
+v1.13.1-56-g34001a9). The bug was due to the fact that Automake-generated
+C compilation rules mistakenly passed the "-c -o" options combination
+unconditionally (even to losing compiler) when the 'subdir-objects' was
+used but sources were only present in the top-level directory.
+
+DONE for automake 1.14
+----------------------
+
+We give a warning in the category 'unsupported' if the 'subdir-objects'
+option is not specified. This should give the users enough forewarning
+about the planned change, and give them time to update their packages
+to the new semantic.
+
+We also make sure to avoid the warning when it would be irrelevant, i.e.,
+if all source files sit in "current" directory (thanks to Peter Johansson
+for suggesting this).
+
+For automake 2.0
+----------------
+
+Make the behaviour once activated by the 'subdir-object' option mandatory.
+With that change, we'll drop support for the "old" behaviour of having
+object files derived from sources in a subdirectory being placed in the
+current directory rather than in that same subdirectory.
+
+Still keep the 'subdir-objects' option supported (as a simple no-op
+now), to save useless churn in our user's build systems.

+For in Automake 2.0 (DONE)
+--------------------------
+
+We will drop split info files in Automake 2.0.
+See automake bug#13351: <http://debbugs.gnu.org/13351>.
+
+Basically, it has been confirmed that the original reason behind
+the existence of split info files was indeed "efficiency,
+especially memory size":
+<http://lists.gnu.org/archive/html/texinfo-devel/2012-08/msg00024.html>
+
+So split info files have lost their reason d'etre on modern systems
+(where even Emacs has become a lightweight program ;-). And you are
+not using an embedded system to read Info documentation, right?
+
+In addition, it appears that the use of split info files (at least
+the way Automake-generated rules have been handling them for a long
+time) can cause real problems in some (admittedly quite corner-case)
+situations; see automake bug#12320: <http://debbugs.gnu.org/12320>.
+
+This change should be completely transparent to the developer (no
+adjustments needed to be made to Makefile.am or other parts of the
+build system). In case some CI system or overly picky build script
+used to rely on that feature, they'll have to be adjusted; but that
+is expected to be a rare occurrence, and thus a price worth pay for
+the nice simplifications and the fixlets this planned change will
+offer us.

+Done in automake 1.13.2:
+------------------------
+
+I have discouraged the use of '.txi' and '.texinfo' suffixes for
+Texinfo inputs (see commit 'v1.13.1-6-ge1ed314') and the generation
+of suffix-less info files (commit 'v1.13.1-4-g2af418d').
+
+This is done to ease transition to Automake-NG (see commits
+'v1.12.1-416-gd5459b9' and 'v1.12.1-392-ga0c7b6a' there), and
+(to a lesser degree) to discourage use of seldom-tested setups.
+
+
+The Future:
+-----------
+
+I have no plans to do the further step of removing support for those
+usages in future Automake versions. That would be a gratuitous
+incompatibility (in Automake-NG, they have been useful because have
+allowed further refactorings and improvements, but those were
+based on GNU make features, and as such have no place in mainline
+Automake).

- # Until Automake 1.6.3, .info files were built in the

- # non-distributed .info files, and non-distributed .texi
- # files.
- #
- # * Non-distributed .texi files is important in some packages
- # where .texi files are built at make time, probably using
- # other binaries built in the package itself, maybe using
- # tools or information found on the build host. Because
- # these files are not distributed they are always rebuilt
- # at make time; they should therefore not lie in the source
- # directory. One plan was to support this using
- # nodist_info_TEXINFOS or something similar. (Doing this
- # requires some sanity checks. For instance Automake should
- # not allow:
- # dist_info_TEXINFOS = foo.texi
- # nodist_foo_TEXINFOS = included.texi
- # because a distributed file should never depend on a
- # non-distributed file.)
- #
- # * If .texi files are not distributed, then .info files should
- # not be distributed either. There are also cases where one
- # wants to distribute .texi files, but does not want to
- # distribute the .info files. For instance the Texinfo package
- # distributes the tool used to build these files; it would
- # be a waste of space to distribute them. It's not clear
- # which syntax we should use to indicate that .info files should
- # not be distributed. Akim Demaille suggested that eventually
- # we switch to a new syntax:
- # | Maybe we should take some inspiration from what's already
- # | done in the rest of Automake. Maybe there is too much
- # | syntactic sugar here, and you want
- # | nodist_INFO = bar.info
- # | dist_bar_info_SOURCES = bar.texi
- # | bar_texi_DEPENDENCIES = foo.texi
- # | with a bit of magic to have bar.info represent the whole
- # | bar*info set. That's a lot more verbose that the current
- # | situation, but it is # not new, hence the user has less
- # | to learn.
- # |
- # | But there is still too much room for meaningless specs:
- # | nodist_INFO = bar.info
- # | dist_bar_info_SOURCES = bar.texi
- # | dist_PS = bar.ps something-written-by-hand.ps
- # | nodist_bar_ps_SOURCES = bar.texi
- # | bar_texi_DEPENDENCIES = foo.texi
- # | here bar.texi is dist_ in line 2, and nodist_ in 4.
- #
- # Back to the point, it should be clear that in order to support
- # non-distributed .info files, we need to build them in the
- # build tree, not in the source tree (non-distributed .texi
- # files are less of a problem, because we do not output build
- # rules for them). In Automake 1.7 .info build rules have been
- # largely cleaned up so that .info files get always build in the
- # build tree, even when distributed. The idea was that
- # (1) if during a VPATH build the .info file was found to be
- # absent or out-of-date (in the source tree or in the
- # build tree), Make would rebuild it in the build tree.
- # If an up-to-date source-tree of the .info file existed,
- # make would not rebuild it in the build tree.
- # (2) having two copies of .info files, one in the source tree
- # and one (newer) in the build tree is not a problem
- # because 'make dist' always pick files in the build tree
- # first.
- # However it turned out the be a bad idea for several reasons:
- # * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
- # like GNU Make on point (1) above. These implementations
- # of Make would always rebuild .info files in the build
- # tree, even if such files were up to date in the source
- # tree. Consequently, it was impossible to perform a VPATH
- # build of a package containing Texinfo files using these
- # Make implementations.
- # (Refer to the Autoconf Manual, section "Limitation of
- # Make", paragraph "VPATH", item "target lookup", for
- # an account of the differences between these
- # implementations.)
- # * The GNU Coding Standards require these files to be built
- # in the source-tree (when they are distributed, that is).
- # * Keeping a fresher copy of distributed files in the
- # build tree can be annoying during development because
- # - if the files is kept under CVS, you really want it
- # to be updated in the source tree
- # - it is confusing that 'make distclean' does not erase
- # all files in the build tree.
- #
- # Consequently, starting with Automake 1.8, .info files are
- # built in the source tree again. Because we still plan to
- # support non-distributed .info files at some point, we
- # have a single variable ($INSRC) that controls whether
- # the current .info file must be built in the source tree
- # or in the build tree. Actually this variable is switched
- # off for .info files that appear to be cleaned; this is
- # for backward compatibility with package such as Texinfo,
- # which do things like
- # info_TEXINFOS = texinfo.txi info-stnd.texi info.texi

+ # Until Automake 1.6.3, .info files were built in the

+ # non-distributed .info files, and non-distributed .texi
+ # files.
+ #
+ # * Non-distributed .texi files is important in some packages
+ # where .texi files are built at make time, probably using
+ # other binaries built in the package itself, maybe using
+ # tools or information found on the build host. Because
+ # these files are not distributed they are always rebuilt
+ # at make time; they should therefore not lie in the source
+ # directory. One plan was to support this using
+ # nodist_info_TEXINFOS or something similar. (Doing this
+ # requires some sanity checks. For instance Automake should
+ # not allow:
+ # dist_info_TEXINFOS = foo.texi
+ # nodist_foo_TEXINFOS = included.texi
+ # because a distributed file should never depend on a
+ # non-distributed file.)
+ #
+ # * If .texi files are not distributed, then .info files should
+ # not be distributed either. There are also cases where one
+ # wants to distribute .texi files, but does not want to
+ # distribute the .info files. For instance the Texinfo package
+ # distributes the tool used to build these files; it would
+ # be a waste of space to distribute them. It's not clear
+ # which syntax we should use to indicate that .info files should
+ # not be distributed. Akim Demaille suggested that eventually
+ # we switch to a new syntax:
+ # | Maybe we should take some inspiration from what's already
+ # | done in the rest of Automake. Maybe there is too much
+ # | syntactic sugar here, and you want
+ # | nodist_INFO = bar.info
+ # | dist_bar_info_SOURCES = bar.texi
+ # | bar_texi_DEPENDENCIES = foo.texi
+ # | with a bit of magic to have bar.info represent the whole
+ # | bar*info set. That's a lot more verbose that the current
+ # | situation, but it is # not new, hence the user has less
+ # | to learn.
+ # |
+ # | But there is still too much room for meaningless specs:
+ # | nodist_INFO = bar.info
+ # | dist_bar_info_SOURCES = bar.texi
+ # | dist_PS = bar.ps something-written-by-hand.ps
+ # | nodist_bar_ps_SOURCES = bar.texi
+ # | bar_texi_DEPENDENCIES = foo.texi
+ # | here bar.texi is dist_ in line 2, and nodist_ in 4.
+ #
+ # Back to the point, it should be clear that in order to support
+ # non-distributed .info files, we need to build them in the
+ # build tree, not in the source tree (non-distributed .texi
+ # files are less of a problem, because we do not output build
+ # rules for them). In Automake 1.7 .info build rules have been
+ # largely cleaned up so that .info files get always build in the
+ # build tree, even when distributed. The idea was that
+ # (1) if during a VPATH build the .info file was found to be
+ # absent or out-of-date (in the source tree or in the
+ # build tree), Make would rebuild it in the build tree.
+ # If an up-to-date source-tree of the .info file existed,
+ # make would not rebuild it in the build tree.
+ # (2) having two copies of .info files, one in the source tree
+ # and one (newer) in the build tree is not a problem
+ # because 'make dist' always pick files in the build tree
+ # first.
+ # However it turned out the be a bad idea for several reasons:
+ # * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
+ # like GNU Make on point (1) above. These implementations
+ # of Make would always rebuild .info files in the build
+ # tree, even if such files were up to date in the source
+ # tree. Consequently, it was impossible to perform a VPATH
+ # build of a package containing Texinfo files using these
+ # Make implementations.
+ # (Refer to the Autoconf Manual, section "Limitation of
+ # Make", paragraph "VPATH", item "target lookup", for
+ # an account of the differences between these
+ # implementations.)
+ # * The GNU Coding Standards require these files to be built
+ # in the source-tree (when they are distributed, that is).
+ # * Keeping a fresher copy of distributed files in the
+ # build tree can be annoying during development because
+ # - if the files is kept under CVS, you really want it
+ # to be updated in the source tree
+ # - it is confusing that 'make distclean' does not erase
+ # all files in the build tree.
+ #
+ # Consequently, starting with Automake 1.8, .info files are
+ # built in the source tree again. Because we still plan to
+ # support non-distributed .info files at some point, we
+ # have a single variable ($INSRC) that controls whether
+ # the current .info file must be built in the source tree
+ # or in the build tree. Actually this variable is switched
+ # off in two cases:
+ # (1) For '.info' files that appear to be cleaned; this is for
+ # backward compatibility with package such as Texinfo,
+ # which do things like
+ # info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
+ # DISTCLEANFILES = texinfo texinfo-* info*.info*
+ # # Do not create info files for distribution.
+ # dist-info:
+ # in order not to distribute .info files.
+ # (2) When the undocumented option 'info-in-builddir' is given.
+ # This is done to allow the developers of GCC, GDB, GNU
+ # binutils and the GNU bfd library to force the '.info' files
+ # to be generated in the builddir rather than the srcdir, as
+ # was once done when the (now removed) 'cygnus' option was

-## Verbosity of FASTDEP rules
-## --------------------------

-## (2) Other people want to see only the important commands--those that
-## may produce diagnostics, such as compiler invocations. They
-## do not care about build details such as dependency generation
-## (the if/then/else machinery in FASTDEP rules). Their point is
-## that it is hard to spot diagnostics in a verbose output.
-## (3) Other people want "make -s" to work as expected: silently.
-## This way they can spot any diagnostic really easily.
-##
-## The second point suggests we hide rules with @ and that we 'echo'
-## only the relevant parts. However this goes against the two others.
-## There are regular complaints about this on the mailing list, but
-## it's hard to please everybody. On April 2003, William Fulton (from
-## clan (3)) and Karl Berry (from clan (2)) agreed that folding the
-## compile rules so that they are output on a single line (instead of 5)
-## would be a good compromise. Actually we use two lines rather than one,
-## because this way %SOURCE% is always located at the end of the first
-## line and is therefore easier to spot. (We need an extra line when
-## depbase is used.)
