   5 #  make -f build/autogen.mk ACLOCAL=aclocal-1.9
   6
   7 # This is a simple Makefile to update the UNIX build system in such a
   8 # way that doing a cvs diff on its output files should reveal only the
   9 # true changes, not meaningless differences due to slightly different
  10 # autoconf or aclocal m4 files.
  11
  12 # For aclocal: All necessary m4 files are located in the build/aclocal
  13 # directory.  Running aclocal -I build/aclocal when using aclocal 1.9
  14 # will result in an aclocal.m4 which uses m4_include for these files.
