+### 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.
