# Relocatable header

# The functions in this file provide support for relocatability of
# Perl scripts.  They should be included near the beginning of each
# Perl script in a relocatable program, by adding @relocatable_pl@
# and causing the script to be expanded with AC_CONFIG_FILES.  A
# small amount of additional code must be added and adapted to the
# package by hand; see doc/relocatable-maint.texi (in Gnulib) for
# details.
#
# This code is based on relocatable.sh.in, and design changes (and
# bugs) should probably be cross-checked with it.

Select pages from a PostScript document.
