Information on Patterns Files:

Patterns files allow some automation based on the output of the forign
program. The first line of the pattern file should specify a seperator for the
subsequent lines, by using it to seperate the words 'pattern', 'action', and
'translation'. Example, using ' ===== ' as the seperator:
    
    pattern ===== action ===== translation

The file follows these headers; the first element on each line should be a
regular expression pattern, followed by an action, followed by a formatting
string. If a line outputted by the forign program matches the pattern, the
action will be applied. The following actions are supported:
    
    respond: the formatted string will be sent to the forign programs stdin
    replace: the formatted string will be printed instead of the original line
    print: the formatted string will be printed along with the original line
    filter: nothing will be printed
    function: the function named by the formatted string from the
        user_functions file will be called.

The formatting strings will be formatted with numbers in braces replaced by
the group from the expression. Example, using the above seperator:

    login: (w+) ===== replace ===== The user {1} has logged in.

Whenever the forign program prints a login message the more verbose version
will be printed to the screen.
