  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.  New versions of autoconf
  40 ### could very well break this arrangement.
  41 ###
  42 ### We omit the invocation of autoconf's initialization function,
  43 ### because it produces Bourne shell code to parse arguments, but we
  44 ### need to parse our own arguments.
  45 ###
  46 ### We use the m4 quoting characters [ ] (as established by the
  47 ### autoconf system) to include large sections of raw sewage - Oops, I
  48 ### mean, shell code - in the final configuration script.
  49 ###
  50 ### Usage: configure config_name
  51 ###
  52 ### If configure succeeds, it leaves its status in config.status.
  53 ### If configure fails after disturbing the status quo,
  54 ###     config.status is removed.
  55
  56
  57 ### Remove any more than one leading "." element from the path name.
  58 ### If we don't remove them, then another "./" will be prepended to
  59 ### the file name each time we use config.status, and the program name
  60 ### will get larger and larger.  This wouldn't be a problem, except
  61 ### that since progname gets recorded in all the Makefiles this script
  62 ### produces, move-if-change thinks they're different when they're
  63 ### not.
  64 ###
  65 ### It would be nice if we could put the ./ in a \( \) group and then
  66 ### apply the * operator to that, so we remove as many leading ./././'s
  67 ### as are present, but some seds (like Ultrix's sed) don't allow you to
  68 ### apply * to a \( \) group.  Bleah.
