Topic: Documentation error on first sample
Note the first example:
http://www.bioinformatics.org/phplabware/internal_utilities/htmLawed/example_settings.htm
$config = array('safe'=>1);
$out = htmLawed($in);
Notice $config is not passed to the function! This is code a lot of people might copy/paste assuming htmLawed looks at $GLOBALS['config'].
