Re: [PATCH] instaweb: added support Ruby's WEBrick server

> running the webrick server with git requires Ruby and Ruby's YAML and
> Webrick libraries (both of which come standard with Ruby). nice for
> single-user standalone invocations.
> 
> the --httpd=webrick option generates a ruby script on the fly to read
> httpd.conf options and invoke the web server via library call. this
> script is placed in the .git/gitweb directory. it also generates a
> shell script in a feeble attempt to invoke ruby in a portable manner,
> which assumes that 'ruby' is in the user's $PATH.
