# This script parses LJ dependency info from all the other files on
|
||
|
|
# that make up the site. Usually that dependency data is at the end
|
||
|
|
# of the files, but in this file it's here at the top for two reasons:
|
||
|
|
# as an example, and because otherwise this script would parse itself
|
||
|
|
# and start at the wrong place. So, here's this file's dependency
|
||
|
|
# data:
|
||
|
|
#
|
||
|
|
# <LJDEP>
|
||
|
|
# lib: Getopt::Long
|
||
|
|
# </LJDEP>
|
||
|
|
#
|
||
|
|
# This file parses files for lines containing <LJDEP> then starts
|
||
|
|
# looking for dependency declarations on subsequent lines until
|
||
|
|
# </LJDEP> is found. Note that leading junk is ignored. The
|
||
|
|
# dependencies are of the form:
|
||
|
|
#
|
||
|
|
# type: item, item, item
|
||
|
|
#
|
||
|
|
# Where type is one of:
|
||
|
|
#
|
||
|
|
# file -- data file
|
||
|
|
# form -- form with method=GET
|
||
|
|
# lib -- perl module or library (append :: if ! /::/)
|
||
|
|
# link -- web link
|
||
|
|
# mailto -- mailto link
|
||
|
|
# post -- form with method=POST
|
||
|
|
# prog -- program that's run
|
||
|
|
# hook -- LJ hook name
