-[+NAME?gnaw - maze game written in ksh93]
-[+DESCRIPTION?\bgnaw\b is a maze game.
-        The player maneuvers a yellow "@" sign to navigate a maze while eating
-        small dots. A level is finished when all the dots are eaten. Five monsters
-        (maw, claw, jitterbug, tentacle and grendel) also wander the maze in an attempt
-        to catch the "@". Each level begins with all ghosts in their home, and "@" near
-        the bottom of the maze. The monsters are released from the home one by one at the
-        start of each level and start their rentless hunt after the player.]
-[q:quiet?Disable use of terminal bell.]

-[+NAME?man - find and display reference manual pages]
-[+DESCRIPTION?The man command displays information from the reference
-	manuals. It displays complete manual pages that you select
-	by name, or one-line summaries selected  either  by  keyword
-	(-k), or by the name of an associated file (-f). If no
-	manual page is located, man prints an error message.]
-[+?write me.]
-[k:keyword?Prints out one-line summaries from the windex database (table of contents) that
-	contain any of the given  keywords. The windex database is created using
-	catman(1M).]
-[l:list?Lists all manual  pages  found  matching name within the search path.]
-[M:mpath?Specifies an alternate search  path  for manual  pages. path is a colon-separated
-	list of directories that contain  manual page directory subtrees. For example, if
-	path  is  /usr/share/man:/usr/local/man, man  searches  for  name in the standard
-	location, and then /usr/local/man.  When used  with  the -k or -f options, the -M
-	option must appear first. Each directory in  the  path is assumed to contain subdirectories of the form man* or sman*  ,
-	one  for each section. This option overrides the MANPATH environment variable.]:[path]
-[s:section?Specifies sections of the manual for man to search. The directories searched for
-	name are limited to those specified by section. section can be a numerical
-	digit, perhaps followed by one or more letters to match the desired section of
-	the manual, for example,  "3libucb". Also, section can be a word, for example,
-	local, new, old, public. section can also be a letter.
-	To specify multiple sections, separate each section with
-	a comma. This option overrides the MANPATH environment variable and the man.cf
-	file.
-	See Search Path below for an explanation of how man conducts its search.]:[section]

-	The method "hist" prints a history of transactions created with the
-	"put" method and the keys to retrive them again using the "get" method.]
-[+?The second arg \bstring\b contains either the string data which should be
