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.
