jughead is an acronym for:
   Jonzy's Universal Gopher Hierarchy Excavation And Display
jughead head can act as a search engine on a prebuilt table
that allows searching through menus, or can create a linear
view of menu space.  When running jughead you can specify
what part of gopherspace you want search tables built or a
linear view thereof.

When running as a search engine, jughead listens out a port
for a connection and a search string. The search string can
contain the boolean operations "AND", "OR", and "NOT" between
words.  If no operator is specified between words, it is an
implied "AND" operation.  For example either:
   "University of utah" or "University AND of AND Utah" will
yield all gopher entries with "university" and "of" and "utah"
in the title.  The case of the letters is irrelevant.  Now
suppose you enter the string "university of utah NOT gopher".
This will return the same information as the first search
except for those entries containing the word "gopher".
Currently there is no way to search on the words "AND", "OR",
or "NOT"; nor is there a way to break an expression into a
group of smaller expressions.  jughead also supports partial
word searches, where the asterik '*' is the wildcard character.
The wildcard character cannot be the first or only character
in a search word, and all characters following the wildcard
are ignored.  For example: both "*", and "*opher" are not
valid, while "go*r" will return all items that have a word
beginning with "go" in the title.  Note that the 'r' following
the asterik is ignored in the search.  The maximum number of
entries returned is 1024 unless you use a special command
described at the end of this document.

All words are broken into smaller words if any word contains
a whitespace character or one of the following characters:
   !"#$%&'()+,-./:;<=>?@[\]^_`{|}~
Thus if a menu item has the name "A sample.file", this is
broken into the three words "A", "sample", and "file.  So if
your search statement is: "sample.file some_thing-else", your
query gets broken into the statment:
"sample AND file AND some AND thing AND else", which will only
return those items with all these words in the menu.

jughead supports some special commands, where each special
command must be preceeded by a question mark '?', and are
listed below:
	?all what
	?help [what]
	?limit=n what
	?version [what]
where 'what' is a standard search string, anything enclosed
in square brackets is optional, and all special commands must
be preceeded with '?'.  And each command is described below:
	?all what	returns all the hits on 'what'.
			Otherwise items will only be returned
			it there are fewer than 1024 items.
	?help [what]	Gives you this document and any
			optional hits on 'what'.
	?limit=n what	Returns the first 'n' items on 'what'.
	?version [what]	Returns the version of jughead and
			any optional hits on 'what'.
Only 1 special command is supported per query, and if any
syntax error is reported as the title to this document.
