ToDo list for KPathSea port

db.c:
	Handle foo.bar.tex entry in ls-R.
	(db_build): use fgets() rather than read_line()

cnf.c:
	Use fgets like db_build.
	Look for texmf/cnf by default rather than texmf.cnf. (22. Jul 1998)
	Set SELFAUTO* variables from program_invocation_name. (5. Sep 1998)

variable.c:
	A hash table for old getenv() calls?

expand.c:
	(kpse_expand_kpse_dot): Don't call getenv() each time. (5. Sep 1998)
	Rewrite brace expansion code: no quoting and LGPL.
	recursive RISC OS paths are not fully expanded?

The riscos_desktop flag should have three states: off, maybe, on. Maybe
means `yes' when an absolute filename is given, otherwise `no'.

General: Allow Unix-style filenames.
dir/foo.tex --> dir.foo*tex or dir/foo*tex
foo.bar.tex --> foo.bar*tex or foo/bar*tex

allow ./foo and ../foo but not /foo

Write mktex{pk,tfm,tex,mf} programs
