I want this manual to be useful both to developers and users of TAME,
so this distinction needs to be made clear.
* doc/tame.texi (Preprocessor): chapter=>appendix.
* src/graph.texi: Top to appendix and raise subsections.
* src/symtable.texi: Top to appendix.
TODOs shouldn't be stored here, and they will get out of sync.
* Makefile.am (tame_TEXINFOS): Remove todo.texi.
* tame.texi: Remove include and menu entry.
* todo.texi: Remove file.
This does not include a great deal of information, but it is a start.
* README.md: Modernize.
* doc/Makefile.am (tame_TEXINFOS): Add `about.texi'.
* doc/about.texi: New file.
* doc/tame.texi: Include it.
Most LaTeX distributions prohibit loading files from parent
directories. This gets around that for PDF builds.
* doc/src: Add symlink.
* doc/tame.texi, src/symtrable.xsl: Use it.
