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