fix caching. cache_get() now returns an array and not a string. thanks to devel.module for illustrating this.

only show published nodes

significantly simplified the vocab_vert() function using the depth parameter offerred in the urls for taxonomy.module

http://drupal.org/node/11517. I have done this using some command line magic:

find . -name README -exec cp '{}' '{}.txt' \; -exec cvs remove -f '{}' \; -exec cvs add '{}.txt' \;

I will update all occurences of 'README' to 'README.txt' in the conrtib CVS,
soon. I'll also rename LICENSE, CHANGELOG etc. files as soon as I get around
to it.

by the coding standards, see CODING_STANDARDS.html). I also unified the
format and the location of the $Id$ tag. It starts with "//" and is placed
on the second line in all *.module files, now.

updated for theme('page') and set_html_head() but head is still busted in this module. we ought to revert recent change in core.
