# Makefile.am:
#   Source file for Makefile.in (and hence Makefile)

# Makefile.am need only be changed on a major version number
# change (e.g. libpng12 --> libpng14).  In that case seach
# this file for every instance of the old base name (libpng12)
# and change to the new one (libpng14), then change the
# -version-number settings below so that the new values have
# the correct major part (first field).
