This is the README file for the describe package.  This package is
designated as version 1.0.2, and consists of the following utilities:

	describe v1.0.2  - show database entries describing the current
                           status of programs

	descc    v1.0.2  - the describe source compiler

	descu    v1.0.2  - the describe source updater

ABOUT DESCRIBE AND DESCC
========================

  This is yet another project I've been sitting on for a while, but have
finally decided to release.  The basic idea of the 'describe' package
(the descc "compiler" and describe itself) is to provide a quick, easy
way of accessing information related to the utilities which so many
different people are releasing these days.  The reason it sat around on
my harddrive so long is I was having qualms about its designated role in
life.  I wasn't sure exactly what I wanted it to do.  Well, I've decided
to KISS for now: descc simply compiles the utility list, which I maintain,
into a (very) simple "database" located in /usr/local/lib/
[alternatively, the full path given in the environment variable DESCDB will be
used, if it is set. sb].  The companion utility 'describe' is used to
fetch information about a particular utility from this "database".

   descc is fairly limited, as is the "database" format itself.  Part of the
KISS (or it wouldn't be out now) design philosophy ;).  Usage is simple:
when you get a new listing (I'll provide monthly updates), simply "descc
<filename>" where <filename> is the name of the newly released update.
descc will simply write over the old database and replace it with the
new.  (Note:  No appendages are allowed by descc.  See descu.)

   As always, coments are appreciated.  And, moreso than on other projects,
I'd appreciate some comments about the direction I'm going in, suggestions
as to where to take this, etc.  I have a feeling that some fields in the
format (eg, FTP:) are rather useless, and I'd like to know what you guys
out there think.

ABOUT DESCU
===========

I think describe and descc were really good ideas; they sure beat the
text file list of Gno utilities that James used to keep.  The one major
shortfall I found was having to manually update the describe database
source every time I wanted to include a new entry.

I therefore wrote descu, the describe updater, which is also rather
limited due to following the KISS principle.

For completeness, I have also added the man pages describe.1, descc.8,
and descu.8.  I briefly pondered having a describe.5, but alas I was too
lazy; you can find the file formats as part of descc.8.

INSTALLATION
============

You can either type "dmake install", or do the following:

	mkdir -p /usr/local/lib
	cp ./describe /usr/local/bin
	cp ./descc    /usr/sbin
	cp ./descu    /usr/sbin
	rm /usr/local/bin/descc

You will also want to do the following, which is NOT done by dmake's
install target:

	rehash
	descc ./describe.source

CHANGES
=======

This details changes to the entire distribution.

v1.02	October 1995
	descc now circumvents a bug in ORCA/C's ftell() function.
	describe can now find entries that are not all lower-case.
	describe will now print the name of entries in the case
		they were entered into the database.
	descu now sorts the describe source file case-insensitive.
	describe and descc can now find the database in a path given
		by the environment variable DESCDB. If DESCDB is not set,
		/usr/local/lib/describe is used, as before.
	A new "Shell:" field has been added to the format of the database.

v1.01	May 1995
	Initial release for descu.
	Added -h and -v flags to describe and descc.
	Common defines and typedefs were extracted to desc.h.
	Descc now exits -1 on failure (vice 0).
	In descc, some more error checking and flushing were added.  Also,
		mygets wasn't dereferencing one of its arguments properly.
	Allocated stack size was increased from 512 to 768 bytes.
	Describe and descc were modified not to be dependant on the size
		of integers.
	Ran source files through indent(1).
	
v1.0	Feb 1994
	Initial release for describe and descc.
