New versions of autoconf ### could very well break this arrangement. ### ### We omit the invocation of autoconf's initialization function, ### because it produces Bourne shell code to parse arguments, but we ### need to parse our own arguments. ### ### We use the m4 quoting characters [ ] (as established by the ### autoconf system) to include large sections of raw sewage - Oops, I ### mean, shell code - in the final configuration script. ### ### Usage: configure config_name ### ### If configure succeeds, it leaves its status in config.status. ### If configure fails after disturbing the status quo, ### config.status is removed. ### Remove any more than one leading "." element from the path name. ### If we don't remove them, then another "./" will be prepended to ### the file name each time we use config.status, and the program name ### will get larger and larger. This wouldn't be a problem, except ### that since progname gets recorded in all the Makefiles this script ### produces, move-if-change thinks they're different when they're ### not. ### ### It would be nice if we could put the ./ in a \( \) group and then ### apply the * operator to that, so we remove as many leading ./././'s ### as are present, but some seds (like Ultrix's sed) don't allow you to ### apply * to a \( \) group.
