Unknown Regular Expression

Hey folks,
I have a regular expression that I found while doing some code analysis .. but I do not know what does it do because I barely know anything about regex codes,
Please help me learn about this.
^([^/]*)/([^\(\ ]*)(?:[^\(]*\(([^\):;]*);([^\):;]*)[^\)]*\)([^,:;]*).*){0,1}
Thanks,
Dev
