# 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.
-R, -p, --pages=PAGES select the given page ranges
-e, --even select even-numbered pages
-o, --odd select odd-numbered pages
-r, --reverse reverse the order of the pages
-q, --quiet don't show page numbers being output
--help display this help and exit
--version display version information and exit
PAGES is a comma-separated list of pages and page ranges; see
