25 | ### Conventions for build systems. | |
26 | ### | |
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. | |
30 | ### | |
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. | |
33 | ### | |
34 | ### * The following `make' variables must be assigned in the top-level | |
35 | ### Makefile, after `mdw-build' has constructed it. | |
36 | ### | |
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'. | |
41 | ### | |
42 | ### The following `make' targets must be available in the top-level | |
43 | ### Makefile. | |
44 | ### | |
45 | ### dist Write to $(distdir).tar.gz a source distribution of | |
46 | ### the package. | |
47 | ### | |
48 | ### distcheck As for `dist', but also build and test the project. | |
49 | ### | |
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. | |
