+word-replace
+
+   Replace *words* with patterns.   Pattern file specifies which patterns
+   to replace on each line.  All patterns are wrapped with perl \\b regexp
+   specifiers.
+
+Usage: $0       [-v] -p pattern-file files to replace
+
+    -v          -- possibly more verbose
+    -p file     -- pattern file
+    -h          -- help
+
+    anything else == this help message
+
+Pattern file looks like this:
+
+# Example:
+# ignores all lines with beginning with # or not exactly 2 fields
+_Dorky_Name  rtems_dorky_name           # comments, and blank lines are cool
+_Dorky_Name2 rtems_dorky_name2          # comments, and blank lines are cool
+NO_MORE_HELP
