[9fans] kerTeX: get_mk_install.rc

[t***@polynum.com]

Hello,

I have tested and corrected various blunders (or adapted for slight
idiosynchrasies of Plan9 utils), and as for Unices users, there is now
a rc(1) script to simplify getting, compiling, installing and generating
the core fonts and dumps.

You will be "cutting edge" mind you! even on LaTeX side (via pkg_latex
the kerTeX packaging system).

As usual, everything is here:

http://www.kergis.com/kertex.html

http://www.kergis.com/en/kertex.html

If something goes wrong, you have some clue who to contact about...

[t***@polynum.com]

And get_mk_install.rc with an obvious typo (for english doc):

READEM -> README hence hget fails.

Fixed version online. (Should test all paths...)
