				Instructions for developing XHPAST.

				= XHPAST Development Builds =

				To develop XHPAST, you need to install flex and bison. These install out of
				most package systems, with the caveat that you need flex 2.3.35 (which is NEWER
				than flex 2.3.4) and some package systems don't have it yet. If this is the
				case for you, you can grab the source here:

				http://flex.sourceforge.net/

				When building, run `make scanner parser all` instead of `make` to build the
				entire toolchain. By default the scanner and parser are not rebuild, to avoid
				requiring normal users to install flex and bison.
