javaswarm is wrapper around "java" that sets the CLASSPATH to the
correct classes/jar files and the LD_LIBRARY_PATH (that points to the
shared libraries) so that you don't need to specify all this yourself.
If your program is purely standalone (i.e. does not rely on any Swarm
libraries) then clearly you don't need it.

A "build" refers to the creation of all of the above.  The usual
procedure is something like:

 $ ./configure --prefix=<place-to-install-it> <other-configure-options>

  creates Makefile's from Makefile.in's

 $ make

  does the actual `make'

The ".am" and ".in" files are used by automake and autoconf to create
the actual Makefiles that are used when you issue the final make.
Most GNU tools and most other GNU/Linux projects are built using this
cycle, it's absolutely necessary to use something like
automake/autoconf on any non-trivial software projects, maintaining
the Makefile's by hand would be a nightmare.

You don't need to edit these files by yourself.  From a user
perspective, look at the README and INSTALL files in the source
distribution of Swarm.  If you want to know the gory details check
