About POD Documentation
The following documentation uses the "Perl On-line Documentation"
(POD) mark up syntax. It is a simple and yet adequate mark up language
for creating basic man pages, and there are converters to html,
MediaWiki, etc. In adittion, the perldoc utility can be used to
display this documentation on the screen by entering:
% perldoc lats
Or else, run this file through cpp to extract the POD fragments:
% cpp -DPOD -P < lats.c > lats.pod
and place lats.pod in a place perldoc can find it, like somewhere in your path.
To generate HTML documentation:
% pod2html --header < lats.pod > lats.html
To generate MediaWiki documentation:
% pod2wiki --style mediawiki < lats.pod > lats.wiki
If you have "pod2html" and "pod2wini" installed (if not, get them from
CPAN), there are targets in the gex.mk fragment for these:
% make lats.html
% make lats.wiki
