#	bootstrap: set up the project and get it ready to make
#
#	Basically, we run autoconf and automake in the
#	right way to get things set up for this environment.
#
#	We also look and see if those tools are installed, and
#	tell you where to get them if they're not.
#
#	Our goal is to not require dragging along anything
#	more than we need.  If this doesn't work on your system,
#	(i.e., your /bin/sh is broken) send us a patch.
#
#	This code loosely based on the corresponding named script in
#	enlightenment, and also on the sort-of-standard autoconf
#	bootstrap script.

# Run this to generate all the initial makefiles, etc.
