man.config file manual page

Here is the manual page you would see if you typed man man.config on a Linux machine:

MAN.CONFIG(5)                        MAN.CONFIG(5)
 
NAME
  man.config - configuration data for man
 
DESCRIPTION
  This file is read by man(1) and contains (a) 
  information on how to construct the search 
  path for man, (b) full path names for various 
  programs like nroff, eqn, tbl etc. used by man, 
  and (c) a list with uncompressors for files with 
  a given extension.  An alternative version of 
  this file can be specified with
 
  man -C private_man.config ...
 
  The command names may be provided with options. 
  Useful options to nroff can be found in 
  grotty(1). For example, instead of the default 
  line

NROFF /usr/bin/groff -mandoc -Tlatin1

one may write

NROFF /usr/bin/groff -mandoc -Tlatin1 -P-u -P-b

in order to suppress underlining and overstriking.
