lbl/Introduction

This is a distribution of a preprocessor, lbl, for nroff and its
kindred.  Lbl allows you to give symbolic labels to objects in a text
file which belong in numbered sequences (e.g.  chapters, figures,
tables, equations) and to refer to them by name; sequence numbers are
assigned automatically.  Hence, it is unnecessary to adjust all
cross-references every time that a new item is inserted into the middle
of a sequence.

Multi-level sequences are supported (similar to the multi-level section
numbers in many macro packages); the user has control over the format
of each level of sequence numbers (roman, arabic, letters).  Many
independent sequences may be used simultaneously, limited only by the
memory available to the program; the same name may be used for items in
several sequences.

The program was written by Chris Miller at Heriot-Watt University,
Edinburgh.  Please report bugs, portability problems or ideas for
improvements to chris@hwcs.uucp ( ....!mcvax!ukc!kcl-cs!hwcs!chris if
you need to be more explicit in your mail path).

As indicated in the attached NOTICE, you are free to pass this to
anyone else; it contains NO code restricted under proprietary
agreements.  If you make alterations, please (a) inform the author and
(b) mark the emendations to the original distribution clearly
(preferably through conditional compilation) -- I desire neither praise
for your brilliance nor scorn for your incompetence!
