iChat to Adium Chat Transcript Converter

/ Published in: PHP

This is kind of a sloppy way of converting iChat transcripts to Adium transcripts.

To get this to work, export your chats using [Logorrhea](http://spiny.com/logorrhea/) (`File > Export Chats...`) then use the exported file as the `$infile` for this script. Also, change `$myscreenname` and `$myname` to your screenname and name, respectively. Finally, run the script in Terminal (`php this_script.php`).

**Note:** For this script to work, you must have PHP, PEAR, and PEAR's Date module installed (type `sudo pear install Date` in Terminal).

Sorry that this is a pain in the ass to get working. I wrote it very quickly for personal use and thought others might get some use out of it.
