The build system uses autoconf 2.57 and automake
1.7. You should modify only the Makefile.am files, which
generate the Makefile.in files (and
the configure script produced by autoconf will generate the
Makefiles from those).
The top-level Makefile.am contains the
SUBDIRS= line which sets up directory recursion, and the
rules for creating source distributions.
To make distributions:
make dist
make dist-client
... will make the full and client distributions respectively. (The client distribution contains everything necessary to compile the client; the full distribution contains everything necessary to compile the server and client.)
Each will make .tar.gz, .tar.bz2,
and .zip files. You can also make only the individual ones
using the make
targets dist-bzip2, dist-gzip, dist-zip.
