NAME

       soelim - interpret .so requests in groff input

SYNOPSIS

       soelim [-Crtv] [-I dir] [files ...]

       It is possible to have whitespace between the -I command line option and its parameter.

DESCRIPTION

       soelim reads files and replaces lines of the form

              .so file

       by  the  contents  of  file.  It is useful if files included with .so need to be preprocessed.  Normally,
       soelim should be invoked with the -s option of groff.

       To embed `\' in the file name, write `\\' or `\e'.  To embed a  space,  write  `\ '.   Any  other  escape
       sequence in file makes soelim ignore the whole line.

       Note  that  there  must  be  no  whitespace  between  the leading dot and the two characters `s' and `o'.
       Otherwise, only groff interprets the .so request (and soelim ignores it).

OPTIONS

       -C     Recognize .so even when followed by a character other than space or newline.

       -Idir  This option may be used to add a directory to the search path for files (both those on the command
              line and those named in .so requests).  The search path is initialized with the current directory.
              This option may be specified more than once; the  directories  are  then  searched  in  the  order
              specified  (but  before the current directory).  If you want to make the current directory be read
              before other directories, add -I. at the appropriate place.

              No directory search is performed for files with an absolute file name.

       -r     Do not add .lf requests (for general use, with non-groff files).

       -t     Don't emit .lf requests but TeX comment lines (starting with `%') giving the current file and line
              number.

       -v     Print the version number.

USAGE

       The normal processing sequence of groff is this:

                 input        sourced
                 file          file
                   |             |
                   v             v
               preprocessor -> troff -> postprocessor
                                             |
                                             v
                                          output
                                           file

       That  is,  files  sourced with .so are normally read only by troff (the actual formatter).  soelim is not
       required for troff to source files.

       If a file to be sourced should also be preprocessed, it must already be read before the input file passes
       through the preprocessor.  This is handled by soelim:

                 input
                 file
                   |
                   v
                 soelim -> preprocessor -> troff -> postprocessor
                   ^                                     |
                   |                                     v
                sourced                               output
                 file                                  file
