Base File Documentation

[jacobsantos]

Major sweeping documentation additions to base PHP files for Trunk.

• Adds file level documentation to all of the base folder PHP files.
• Adds function documentation to most of the PHP files in the base folder.
• Ignores class level documentation for wp-app.php and xmlrpc.php files.

Open for whether this should also be added to 2.5.

Base file phpdoc documentation based of r7989

(In [7991]) File file level phpdoc from jacobsantos. see #7037

Corrections to late night ramblings and additions to wp-login.php based off off of r7991

I corrected the late night ramblings to the index.php file and added the file level documentation to index.php.

Am I to assume that the documentation to wp-config-sample.php is not going to be added?

(In [7992]) File file level phpdoc from jacobsantos. see #7037

patch isn't applying the wp-config-sample.php changes for some reason. I'll try to convince it to obey.

Rest of the base functions will be in new patch. Closing as complete.
