+The mkshadow programs makes a "shadow tree" of a directory tree.
+It logically copies all of the "MASTER" directory into ".".
+However, ordinary files, and RCS/SCCS directories are "copied"
+by creating a sybolic link to the corresponding file in MASTER.
+
+The wildmat.c file is by Rich Salz, and from comp.sources.misc, volume 17.
+The savedir.c file is lightly modified from the version written
+by David MacKenzie for GNU fileutils; the Free Software Foundation
+has graciously agreed to waive their usual copyright so this
+program can be distributed by the X Consortium.
+
+If you have problems compiling savedir.c, try setting the DIRENT make
+variable as suggested in the Makefile.
+
+ * Usage: mkshadow [-X exclude_file] [-x exclude_pattern] ... MASTER
+ * Makes the current directory be a "shadow copy" of MASTER.
+ * Sort of like a recursive copy of MASTER to .
+ * However, symbolic links are used instead of actually
+ * copying (non-directory) files.
+ * Also, directories named RCS or SCCS are shared (with a symbolic link).
+ * Warning messages are printed for files (and directories) in .
+ * that don't match a corresponding file in MASTER (though
+ * symbolic links are silently removed).
+ * Also, a warning message is printed for non-directory files
+ * under . that are not symbolic links.
+ *
+ * Files and directories can be excluded from the sharing
+ * with the -X and -x flags. The flag `-x pattern' (or `-xpattern')
+ * means that mkshadow should ignore any file whose name matches
+ * the pattern. The pattern is a "globbing" pattern, i.e. the
+ * characters *?[^-] are interpreted as by the shell.
+ * If the pattern contains a '/' is is matched against the complete
+ * current path (relative to '.'); otherwise, it is matched
+ * against the last component of the path.
+ * A `-X filename' flag means to read a set of exclusion patterns
+ * from the named file, one pattern to a line.
