       soelim - interpret .so requests in groff input


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

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


       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).


       -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

       -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.


       The normal processing sequence of groff is this:

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

       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:

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