This is a module that can be placed on any php3 page to allow users to add
chinaitpower.comyyuAKMNxb32xtTEQbDZoRzffn
their comments. The comments are stored in a file in the current directory,
whose name is constructed by adding ".comment" to the calling page's name,
chinaitpower.comyyuAKMNxb32xtTEQbDZoRzffn
and merged into the calling page dynamically. (The calling page is not
chinaitpower.comyyuAKMNxb32xtTEQbDZoRzffn
modified.)

I wrote this because I wanted a simple way to add this functionality to my
chinaitpower.comyyuAKMNxb32xtTEQbDZoRzffn
pages without requiring that mySQL be available.

In the message input, blank lines are converted to paragraph tags. No other
chinaitpower.comyyuAKMNxb32xtTEQbDZoRzffn
conversions are applied. If you don't want your users to be able to input
chinaitpower.comyyuAKMNxb32xtTEQbDZoRzffn
html, uncomment the "strip_tags" line.

Put this module in some convenient location and then embed it in your pages
chinaitpower.comyyuAKMNxb32xtTEQbDZoRzffn

chinaitpower.comyyuAKMNxb32xtTEQbDZoRzffn

chinaitpower.comyyuAKMNxb32xtTEQbDZoRzffn
require("/some/full/path/annotate.php3");
chinaitpower.comyyuAKMNxb32xtTEQbDZoRzffn
or, relative to the docroot:
chinaitpower.comyyuAKMNxb32xtTEQbDZoRzffn
require($DOCUMENT_ROOT . "/relativepath/php3");
