2022-08-18 G. Branden Robinson <g.branden.robinson@gmail.com>
* chem.pl: Refactor.
- Rename scalars.
Copyright -> copyright
Program_Version -> chem_version
Groff_Version -> groff_version
Chem_Name -> chem
before_make -> is_in_source_tree
- Rename hash.
at_at -> makevar
- Drop unused hash member `$makevar{'BINDIR'}`.
- Drop scalar `Groff_Version_Preset`, which apparently hadn't
been updated since groff 1.20. Instead, follow grog(1) and
set the `groff_version` scalar to "DEVELOPMENT" if this is
the version from the groff source tree. Overwrite its value
with that determined by make(1) if available.
- Tighten usage and version messages; make the latter more
conformant with the format recommended in the GNU Coding
Standards. Explicitly identify license as GNU GPLv2.
(usage): Refer to "pic" with its command prefix if it is known
to have one. (If running "unbuilt", we have no way to know.)
2022-08-18 G. Branden Robinson <g.branden.robinson@gmail.com>
* chem.pl: Stop copying "pic.tmac" (fallback troff macro
definitions) into the output. It might not be necessary and it
is inappropriate to do so if a macro package offers its own
definitions or the user has made other arrangements on the
command line. (The same thing can be achieved with the "-mpic"
argument to the formatter or a front end.) Bump version number.
2022-06-15 G. Branden Robinson <g.branden.robinson@gmail.com>
* chem.1.man: Fix markup nits. Use idiomatic input style,
placing newlines after sentences and commas. Also put an empty
request between sentences.
Fixes <https://savannah.gnu.org/bugs/?51328>.
2022-04-12 Ingo Schwarze <schwarze@openbsd.org>
Delete the harmful, ill-designed, buggy, and essentially
unmaintained and untested --with-doc option of the configure
script. See the NEWS file for more details on the rationale.
* chem.am: Delete three BUILD_EXAMPLES conditionals.
2020-04-22 G. Branden Robinson <g.branden.robinson@gmail.com>

* Makefile.sub (install_examples): Use `find', not shell globs.
Instead of using rm(1) two times with shell globs the expansion of
which will include subdirectories (thus resulting in error
messages), use find(1) and its `-exec' operand.

$(make{_,_install_,_uninstall_}examples).

* 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>

* 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.
