+# NAME
+
+redo-subst - substitute file suffixes
+
+# SYNOPSIS
+
+redo-subst suffix replacement [sources...]
+
+
+# DESCRIPTION
+
+redo-subst takes a file suffix, a replacement suffix and
+a list of file names on which the file suffix shall be substituted
+with the replacement suffix. For every file name that ends
+with the specified suffix, the suffix is removed, the
+replacement suffix is appended and the resulting file name
+is printed out. File names whose suffix does not match
+are printed out unmodified.
+
+# REDO
+
+Part of the `redo`(1) suite.
+
+# CREDITS
+
+The original concept for `redo` was created by D. J.
+Bernstein and documented on his web site
+(http://cr.yp.to/redo.html).  This independent implementation
+was created by Avery Pennarun and you can find its source
+code at http://github.com/apenwarr/redo.
