This is deroff release 1.6, a free implementation of the standard unix command. Deroff removes roff constructs from documents for the purpose of indexing, spell checking etc. My own implementation is a little smarter than traditional implementations, because it knows about certain -man and -mm macros. It is able to generate a word list for spell checking tools or omit headers for sentence analysis tools. It can further generate cpp-style #line lines.
