* Makefile.sub (all, MOSTLYCLEANADD): Add `examples/122/README'.
(examples/122/README): New target.

* chem.pl: Prepare for groff version 1.20.
2008-01-04 Werner LEMBERG <wl@gnu.org>
* chem.man: Insert `\:' in URLs where appropriate.
2007-02-06 Eric S. Raymond <esr@snark.thyrsus.com>
* chem.man: Change .UR/.UE and .MT/.ME so the start macro no longer
takes a second argument that is pasted to the end of the generated
text. Instead, the end macro takes an argument that does the same
thing.
2007-02-02 Werner LEMBERG <wl@gnu.org>
* chem.man: Further refinements and normalizations.
2007-02-02 Eric S. Raymond <esr@snark.thyrsus.com>
* chem.man: Converted to use .SY/.OP/.YS and for cross-viewer
portability. Conversion checked using the protocol described in
tmac/TESTING-HINTS.

________________________________________________________________
* release of chem 0.3.1
* chem.man: Add information about example files.
2006-11-10 Werner LEMBERG <wl@gnu.org>
* chem.man1: Rename back to...
* chem.man: This.
Use @G@, @MACRODIR@, and @DATASUBDIR@.
* Makefile.sub (CLEANADD, all): Don't handle chem.man.
(chem.man): Remove rule.
(chem): s/tmacdir/MACRODIR/, s/picdir/PICDIR/.
* chem.pl: s/tmacdir/MACRODIR/, s/picdir/PICDIR/.
2006-11-10 Bernd Warken <groff-bernd.warken-72@web.de>
________________________________________________________________
* release of chem 0.3.0
* chem.man1: Rename `chem.man' to translate some `@...@'
constructs. Some minor corrections. Remove some unused macros.
* examples/README.txt, examples/122/README: Add information on
`roff2*' programs.
* chem.pic: Rename `macros.pic'.
* Makefile.sub, chem.pl: Replace `macros.pic' by `chem.pic'.
2006-11-09 Werner LEMBERG <wl@gnu.org>
* chem.man: Revised.
2006-11-08 Bernd Warken <groff-bernd.warken-72@web.de>
________________________________________________________________
* release of chem 0.2.0
* pic.tmac: Remove this file. Use instead the installed pic.tmac
in $(tmacdir).
* Makefile.sub, chem.pl:
- Install macros.pic to $(tmacdir)/pic/chem.pic.
- Remove parts with `libdir'.
2006-11-07 Werner LEMBERG <wl@gnu.org>
* Makefile.sub: Add and fix $(srcdir) where necessary to make it
compile with srcdir != builddir. Other minor fixes improvements.
2006-11-07 Bernd Warken <groff-bernd.warken-72@web.de>
________________________________________________________________
* release of chem 0.1.2
### `chem' works now with all example files (examples/*.chem and
examples/122/*.chem).
* examples/122/README: Add some information on the example files.
* examples/122/chAi_poly_vinyl_chloride.chem: Use .ps with
argument `-2' and recall `.ps +2' at the end of the file. This
stops the size shift in the following files.
* examples/122/ch6b_dna.chem: Make the file runnable, it works
now.
* examples/reserpine.chem: Change access to `begin chem'.
* chem.man:
- Fix the BUGS section.
- Correct the name of the macro file to `macros.pic'.
- Extent section DESCRIPTION and LANGUAGE.
- Moieties and Strings: Rewritten section about moieties and
double quoted strings.
* chem.pl:
- parameter check: Add filespecs only when non-empty file.
- Set $Last_Type to $OTHER for the `pic' command.
- joinring(), label(), labsave(), reduce(): Remove these functions.
- `[', `]', `{', `}', `define': Make these and the defined
functions commands for `chem' without using the `pic' word.
- @Words: Fix it such that all double quoted strings are
completely in an element.
- `Last: ': Remove this prefix from all commands that are related
to `pic'.
### global variables
* chem.pl:
- $Line: Add this variable to store the unchanged input line.
- %Params: Add the variables from setparams() to this hash.
- %Types: Add BOND, MOL, RING, OTHER from init() to this hash.
- %Put: Move %put to this.
- %Dbl: Move %dbl to this.
- %Labtype: Move %labtype to this.
- %Aromatic: Move $aromatic to this.
- %Dc: Move %dc to this.
- %Nput: Move $nput to this.
- %Define: New hash for storing the names of the `define'
constructs during `chem'. Use the elements in `%Define' as `chem'
commands.

source file <groff-top-source>/tmac/pic.tmac.
* Makefile.sub: Make file for the groff system.
* ChangeLog: This file.
* chem.man: Manual page for the Perl version of chem.

* awk version of chem
chem is a roff preprocessor that generates chemical structure
diagrams suitable for the pic preprocessor. The original version
of chem is an awk script written by Brian Kernighan. This project
is a rewrite of chem in Perl.
