### Conventions for build systems.
###
### This script is designed to work with a variety of `make'-based build
### systems, but there are a number of conventions which must be followed if
### this is going to work properly.
###
###   * There must be a `configure.ac', `configure.in', or `.links' file, or
###	a `.git' directory in the project top-level, so that we can find it.
###
###   * The following `make' variables must be assigned in the top-level
###	Makefile, after `mdw-build' has constructed it.
###
###	distdir		The name of the top-level project directory in the
###			source distribution, and the base name for
###			distribution archives; should be of the form
###			`PROJECT-VERSION'.
###
###	The following `make' targets must be available in the top-level
###	Makefile.
###
###	dist		Write to $(distdir).tar.gz a source distribution of
###			the package.
###
###	distcheck	As for `dist', but also build and test the project.
###
###  * The source distribution constructed by `make dist' must contain a file
###	$(distdir)/RELEASE containing the release name.  This isn't currently
###	tested, but it might be later.
