Re: [Groff] Introduction

[D. E. Evans]

   In the case of SGR sequences, unless the user specifically uses the
   `--enable-sgr' option, `configure' will attempt to run the specified
   `nroff' command, to format a minimal manpage, and `grep' the output for
   an identifiable SGR sequence, before adding the `-c' option to the
   configured `nroff' command.

   As noted above, all this configuration info goes in the `man.conf' file.
   This may be modified, even after installation, to adjust the behaviour
   of `man';  `groff' documentation indicates how it may be necessary to
   adjust the settings in `man.conf', and also identifies alternative
   mechanisms for achieving similar effects, through environment variable
   settings.  IMHO, this is as far as `groff' should be expected to go,
   in this respect.

Thank you for this explanation.
