 # Erebus IRC bot - Author: Erebus Team

+# module for 's/regex/replacement/' style correction
+# warning: arbitrary regex's are generally capable of various DoS attacks on CPU/memory usage. use with caution.

-# however, if it is disabled it will be silently ignored, and if it is unloaded at runtime it won't cause this one to unload.

-# basically, softdeps are things this module will use if available, but does not require (no errors will occur if it's not loaded)
-# for example, @lib.help() will attempt to use the help module, but swallow errors if it is not loaded
