[Automake-ng] [PATCH 3/4] [ng] dist: rename some non-public vars to make


From: Stefano Lattarini
Subject: [Automake-ng] [PATCH 3/4] [ng] dist: rename some non-public vars to make clear they are internal
Date: Sun, 6 May 2012 18:35:29 +0200

The variable $(DISTFILES), $(DIST_COMMON) and $(DIST_SOURCES) have never
been documented, and they were always intended to be internal variables.
This is absolutely not evident from their names, though.  So rename them
like this:

    DISTFILES     =>  am__dist_files
    DIST_COMMON   =>  am__dist_common
    DIST_SOURCES  =>  am__dist_sources

* NG-NEWS: Update.
* automake.in: Adjust code and comments.
* lib/am/configure.am, lib/am/data.am, lib/am/java.am, lib/am/lisp.am,
lib/am/python.am, lib/am/scripts.am, lib/am/texi-vers.am: Likewise.
* lib/am/distdir.am: Likewise, and related variable renamings.
And throw in a few improvements to comments since we are at it.
* Several tests: Adjust.
* syntax-checks.mk: Add rules (and supporting variables) verifying
that the obsolete 'DIST*' variables are actually not used anymore.
