TODO:
- re-implement macros from opmac-rest.opm
- add unicode math support (from uni-math.tex from csplain)
- re-implement usebib, bib-style.opm
- add modules support (for example opmac-bib)
- write more and better documentation
- ...
DOC:
- optex-doc.tex optex-doc.pdf
- about Font selection system: ....... files: fonts-select.opm, fonts-opmac.opm,
fonts-resize.opm, f-heros.opm, f-lmfonts.opm
fams-ini.opm
- about user/internal name spaces .... files: prefixed.opm, math-macros.opm
- additional doc is in more files...
NOTES FOR TESTERS:
- We don't want to keep absolutely backward compatibility. For example obscurities like
\z@, \p@, \f@@t are not supported.
- The page origin is at left upper corner of the paper (no at 1in, 1in coordinates).
- The default papersize is A4 with 2cm margins (no letter with 1in margins].
Use \margins macro to change these parameters.
- Only few 8bit fonts are preloaded in format. Use \fontfam[LMfonts] (or select another
fonts family by \fontfam[?]) at beginning of document. Unicode fonts will be loaded.
- The accents macros \v, \' are undefined, Use native characters š,č,é, etc.
If you expicitly needs this old feature, use \oldaccents macro.
- The font switchers like \_tenrm, \_tenbf have only internal names, i.e
\tenrm, \tenbf are undefined.
