# Process this with autoconf to create configure

# There is a bit of documentation of the obvious.  I did this for friends
# who said autoconf/automake was confusing.  Hopefully, this will serve
# as a good example.   -- bkuhn

# I now always use this as my template when I start a new project, so the
# over-verbose comments live on.  -- bkuhn

# If you modify the way configure options work or add new options, be sure
# to update the README file appropriately.

# AC_INIT is required by autoconf.  The arg is a unique source file
# (which is needed so it knows the source is really there).

AC_INIT(pdfdiff.in)

# This lets autoconf know we are using automake.  It's the name of the 
# program and the current version.  It's important to *only* set the version
# number here.

# If you update the version number, make sure you start a NEWS section.

# update README and INSTALL if you change the version number of Perl we need
