This is for those who want to directly map UNIX file names which cannot be represented on Windows/DOS. The mangling of names is not always what is needed. In particular you may have documents with file extensions that differ between DOS and UNIX. For example, under UNIX it is common to use .html for HTML files, whereas under Windows/DOS .htm is more commonly used. So to map html to htm you would use: (*.html *.htm). One very useful case is to remove the annoying ;1 off the ends of filenames on some CDROMs (only visible under some UNIXes). To do this use a map of (*;1 *;). no mangled map (*;1 *;)
