37 ### Since Emacs has configuration requirements that autoconf can't
38 ### meet, this file is an unholy marriage of custom-baked
39 ### configuration code and autoconf macros.
41 ### We use the m4 quoting characters [ ] (as established by the
42 ### autoconf system) to include large sections of raw sewage - Oops, I
43 ### mean, shell code - in the final configuration script.
45 ### Usage: configure config_name
47 ### If configure succeeds, it leaves its status in config.status.
48 ### If configure fails after disturbing the status quo,
49 ### config.status is removed.
52 ### Remove any more than one leading "." element from the path name.
53 ### If we don't remove them, then another "./" will be prepended to
54 ### the file name each time we use config.status, and the program name
55 ### will get larger and larger. This wouldn't be a problem, except
56 ### that since progname gets recorded in all the Makefiles this script
57 ### produces, move-if-change thinks they're different when they're
60 ### It would be nice if we could put the ./ in a \( \) group and then
61 ### apply the * operator to that, so we remove as many leading ./././'s
62 ### as are present, but some seds (like Ultrix's sed) don't allow you to
63 ### apply * to a \( \) group. Bleah.
