file: README for version 0.92 (November 1999) release of LTX2X ---
A LaTeX to X Autotagger
FUNCTION
The LTX2X program, which is written in C, replaces LaTeX commands
in a LaTeX document by user-defined strings. In essence, LaTeX tags can
be replaced by other kinds of document tags (e.g. HTML/SGML or RTF tags),
or can be removed altogether. The program also has an unsophisticated
pretty-print capability.
The replacement strings for the LaTeX commands are specified
in a command table file, which can be created simply via any text
editor. For more advanced users an interpreter for the EXPRESS-A
programming language is also included. EXPRESS-A includes STRING, LIST
and ENTITY types as as primitives of the language, as well as the
usual REAL, INTEGER and LOGICAL types. Regular expressions are also
an integral part of EXPRESS-A. The interpreter also includes an
interactive source level debugger for EXPRESS-A.
The supplied command tables include facilities for, among others:
o deTeXing and pretty-printing
o Conversion from LaTeX tagging to HTML tagging
The 100+ page user manual is supplied as LaTeX source, Postscript,
and in deTeXed and HTML forms, the latter two being automatically
generated by running LTX2X on the LaTeX source.
LTX2X is compilable by at least the GNU gcc compiler.

INSTALLATION
ltx2x is written as a parser for LaTeX. The main source is
in l2xlib.c. Source for the lexer is in l2x.l which has to be
processed by flex (or equivalent) and the parser is in l2x.y
which is intended to be processed by bison (or equivalent).
Support functions are in files l2xacts.c, l2xusrlb.c, srchenv.c
and getopt.c. After the lexer and parser files are processed,
all the code files must be compiled and linked to form the executable.
The syntax of the command table has been extended and modified.
The printct program will convert a command table in the original
syntax to the new syntax.
Via Make
--------
0. Read the manual
1. Edit the first part of makefile to match your system's configuration.
----- For the ltx2x program
If you are feeling brave, do `make all'. Otherwise continue as below.
2. Do `make' (processes lexer and parser and compiles and links the program)
3. (Optional) Set the environment variable LTX2XTABLES to the
directories where command table files might be located
4. Test the program
5. Do `make install' (moves the binary into its final location)
6. Do `make manpage' (edits the manpage and copies it to its working location)
7. Do `make ctables' (copies the command tables to their working location)
8. Do `make doc' (copies the user manual sources to their final location)
9. Do `make clean' (deletes the object code, yacc output, and edited
manpage files)
----- For the printct program, if desired and preferably after installing ltx2x
10. Do `make printct' to compile printct.c.
11. Do `make installprintct' to move the binary to its final destination.
12. Do `make cleanprintct' to delete printct binary and object files
By Hand
-------
0. Read the manual.
Steps 1 and/or 2 below are only required if changes have been made
to the files l2x.y and/or l2x.l, respectively.
1. Run bison on l2x.y. Rename y.tab.c to l2xytab.c and rename
y.tab.h to l2xytab.h
2. Run flex on l2x.l. Rename lex.yy.c to l2xlexyy.c.
3. Compile all the .c files
4. Link the compiled code to form the final program binary
5. (Optional) Set the environment variable LTX2XTABLES to the
directories where command table files might be located
6. Test the program
7. Move the binary to its final destination
8. Edit the manpage file and copy it to its working location, renaming
it appropriately
9. Copy the example .ct files to their working location
10. Copy the manual source filers to their final location
11. Compile printct.c and move the binary to its final destination
12. Remove intermediate files
