# info.pl
#
# Create SUBJECT.t files from the Info Pages.
#
# written by Ken Stevens
#
#
# DESCRIPTION:
# info.pl reads all of the info pages and creates a table of contents
# for them organized by subject.
#
# Info consists of pages organized into chapters and subjects. Each
# page is about a topic. The page for topic ITEM is in info file
# info/ITEM.t. An info page's chapter is the first argument of its
# .TH request. It belongs to a subject if that subject appears in its
# .SA request ("SEE ALSO") _and_ that entry is not the name of another
# info page. An info page may belong to more than one subject.
#
# For example, the .SA request of headlines.t contains "newspaper" and
# "Communication". Since there's already an info page called
# "newspaper.t", but there is no "Communication" info page, the
# headlines info page is considered to be a member of the
# Communication subject.
#
# This script reads GNUmakefile and sources.mk to find info sources.
# It reads existing subjects from subjects.mk, and updates that file.
# It creates a file info/SUBJECT.t for each SUBJECT, and a table of
# subjects info/TOP.t.
#
# REQUIREMENTS:
# info.pl requires perl5 to run. If you don't have version 5 of perl, then
# you'll either have to install it, or you'll have to get someone to create
# your Subjects.t files for you.
#
# HOW TO RUN IT:
# Run "info.pl" at the root of the build tree.
# --- Global variables ---
# @Subjects Existing subjects
# @Chapters Existing chapters
# $filename The name of the current info file
# $chapter{TOPIC} TOPIC's chapter (first arg to .TH)
# $desc{TOPIC} A one line description of TOPIC (second arg to .NA)
# $level{TOPIC} TOPIC's difficulty level (arg to .LV)
# $see_also{TOPIC}
# TOPIC's SEE ALSO items (.SA argument)
# $sanr{TOPIC} Line number of TOPIC's .SA request
# $subject{$subj}{$chap} = "item1\nitem2\n..."
# Topics in that subject organized by chapter.
# $largest{$sub} The largest topic name in that subject (used for
# column formatting)
#
# --- File handles ---
# F Filehandle for info page sources and makefiles
# SUBJ Filehandle for Subject.t
# TOP Filehandle for TOP.t
#
# --- Functions ---
#
# read_make_var Read a variable value from a makefile
# parse_file Check the .TH, .NA, and .SA fields & parse them
# parse_see_also Create %subject from %see_also
# set_subject Add a new entry to %subject and possibly to %largest
# create_subj Create a Subject.t file
# create_subjects Remove the old Subject.t files and create new ones
# flush_subj Print a row of Subjects to TOP
# error Print an integrity error to STDERR and exit with code 1.
