# CONFIGURE: PBMPLUS's support for TIFF files depends on the library from
# Sam Leffler's TIFF software package.  To configure PBMPLUS to use the
# library: first, if necessary, fetch and build the TIFF software.  If
# you're using FreeBSD, you can just get your sysadmin to cd to
# /usr/ports/graphics/tiff and do a make install.  Finally, uncomment
# the following seven definitions.
#
# Libtiff is pretty good about portability, but there are some machines
# it has problems on.  If you run into problems, you may wish to contact
# the libtiff folks directly.

# CONFIGURE: Normally the Makefile builds and installs separate binaries for
# each program.  However, on some systems (especially those without shared
# libraries) this can mean a lot of space.  In this case you might try
# building a "merge" instead.  The idea here is to link all the binaries
# together into one huge executable, with a tiny dispatch program as the
# main.  Then the merged binary is installed with file-system links for
# each program it includes.  The dispatch routine can tell which program
# to run by looking at argv[0].
#
# Note that if you make a "merge", the executables don't get created
# until you do the install.
