Plugin: Configurable Prompt

Description:
	This plugin allows the user to configure their prompt using a config.fig
file located in the directory they are running the shell from. It will search 
for a line in the file starting with "PROMPT=" and parse the text in the 
qutations following it into a prompt. If the PROMPT= line is missing or 
invalid(i.e. no or missing quotes) then it displays the default prompt. The
default prompt is also displayed if the file itself is missing.

Note: The shell must be started up in the same folder containing the 
config file to detect it. Afterwards the workign directory can change 
via a command like "cd" and it will not affect the plugin.

The plugin uses the following strings to reference system information:

/u: The current username.
/h: The name of the current host machine.
/w: The name of the current working directory.

To use one of these flags in the prompt use and additional '/' so:

"//u@//h://w>" would become the prompt /u@/h:/w>

An example prompt: 
	
	PROMPT="/u@/h:/w>"
