This is the shell script, which is a wrapper around Pidgin2Adium::Logs.
Call it like so:
<tt>pidgin2adium_logs.rb -i ~/in_logs/ -o ~/out_logs/ -l AIM.myscreenname -a me,screenname,my_pidgin_alias,other_pidgin_alias</tt>
For <tt>-a/--aliases</tt>, there is no need to use spaces or capitalization, since spaces will be stripped out and the aliases will
be lowercased anyway.
