Man-support-local-filenames

Man-support-local-filenames is a compiled Lisp function in `man.el'.

(Man-support-local-filenames)

Return non-nil if the man command supports local filenames.
Different man programs support this feature in different ways.
The default Debian man program ("man-db") has a `--local-file'
(or `-l') option for this purpose. The default Red Hat man
program has no such option, but interprets any name containing
a "/" as a local filename. The function returns either `man-db'
`man', or nil.
