 tlsclient: tlsclient(1) for unix

-tlsclient comes with two programs, tlsclient itself and 9cpu which uses tlsclient

-to connect to a 9front cpu server and acts as rcpu(1).

+This repo contains three programs, tlsclient itself, 9cpu and git-remote-hjgit.

+9cpu acts as rcpu(1).

+Git-remote-hjgit is a git remote helper for unix git that allows use of hjgit repos.

-Most of this code is pillaged from jsdrawterm: https://github.com/aiju/jsdrawterm

+Most of the tlsclient code is pillaged from jsdrawterm: https://github.com/aiju/jsdrawterm

 Usage:

 	tlsclient [ -u user] [ -h host ] [ -a auth ] -p port cmd...

 	9cpu [ -u user ] [ -h host ] [ -a auth ] cmd...

+Example:

+	9cpu -u moody -h shithub.us -a p9auth.shithub.us newrepo tlsclient

+

+	# with git-remote-hjgit in your $PATH

+	git clone hjgit://shithub.us/user/repo

+

 Bugs:

-	Currently 9cpu uses gnutls, a better alternative is welcome.

+	Currently tlsclient uses gnutls, a better alternative is welcome.
