NAME

       gather_stx_titles - gather title declarations from Stx documents

SYNOPSIS

       gather_stx_titles [ -f from-suffix ] [ -t to-suffix ] [ m4 options ] file [ file ... ]

DESCRIPTION

       gather_stx_titles  digs	out Stx metadata declarations from the listed files, and dumps the title and document ID information as m4 defini-
       tions into standard output.  This information can later be used by w_crosslink to link the documents by their metadata.

       Why is this useful?  Well, imagine that you have a large site with a lot of cross-linking.  A document's name will appear in  many  places:
       in  the	link menu (if you have one), and in the body of different pages where it is cross-linked from.	gather_stx_titles lets you put all
       the information in one place and where it belongs, i.e. the file itself.  You'll be glad if you did, when the time comes to change document
       titles or move the documents around; especially so if your website has multilingual magic.

OPTIONS

       gather_stx_titles uses m4 internally and will accept any option m4 accepts.  In addition to those, it takes the following options:

	  -f from-suffix
		 In  the  filename  data,  substitute  away the suffix from-suffix.  Actually, from_suffix may be a regular expression; stupid but
		 true, in GNU m4 it is a "traditional" regexp, whereas in BSD m4 it is an "extended" regexp.  Default to  no  suffix  (nothing	to
		 take away).

	  -t to-suffix
		 In  the  filename  data,  substitute  the  suffix taken away by from-suffix with to-suffix.  If from-suffix is nil (the default),
		 append to-suffix to all filenames.

	  -p prefix
		 Strip away the prefix given by (regular expression) prefix from filenames.  The equivalent of -t for this does not exist, because
		 you can specify a directory prefix to w_crosslink by w_base.

	  --version, -V
		 Just show version information and exit.

	  --help, -?
		 Just show a short help message and exit.

EXAMPLES

       I guess most of the time you will want to automate the use of gather_stx_titles, for example with a Makefile like this:

       SOURCES = $(wildcard *.stx)
       TARGETS = $(SOURCES:.stx=.html)

       all: $(TARGETS)

       titles.m4: $(SOURCES)
	       gather_stx_titles -f stx -t html $^ > $@

       %.html: %.stx titles.m4
	       stx2any -T html titles.m4 $< > $@

       If you don't want to be quite so correct, drop the .html dependency on titles.m4 or titles.m4 dependency on SOURCES.  Using temporary files
       is not necessary: this should also work:

       $ gather_stx_titles *.stx | stx2any - mydoc.stx
