The goal of miwm is to be a fully functional window manager, while retaining a very spare (Zen or Spartan, as you please) appearance and command-set.
The shell wildcards * and ?, as well as shell brace notation using [ and ], are interpreted correctly by miwm. It is possible to pass wildcards to the program without the wildcards being intercepted by the shell by setting noglob (in csh) or by quoting the wildcards. To delete a file that actually has a wildcard in its name, you must precede the quoted wildcard with a quoted backslash.
If no files are specified on the command line, miwm goes into interactive mode. In interactive mode, the user is prompted to enter files to be restored, one file per line. Typing a carriage return on an empty prompt line exits the program.
Wildcards and quoting backslashes can be entered directly at the prompt without any shell interference (which is the main reason there is an interactive mode).
