Added files:
/livedocs livedoc_funcs.php pregenerate.php xml_classes5.php
Modified files:
/livedocs configure.in livedoc.php mkindex.php
/livedocs/themes/default html_format.php
Log:
Big commit; will be a little unclear what has changed.
- Split the functions out from livedoc.php and into livedoc_funcs.php
- Added PHP 5 version of xml_classes5.php; assignment using the reference
operator leaks massive amounts of memory and will not be fixed.
- Added pregenerate.php which should be run using PHP 5 (see above!) only to
generate the entire manual as individual html pages.
- Some minor corrections to Ilia's perf tweaks
- Smarter entity handling
Discovery:
do_nav() is way too slow; don't attempt to pregenerate anything until it is
tuned, unless you are a gentoo user with CPU to burn.
