       soelim - interpret .so requests in groff input

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

       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 op-
       tion 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).

       Whitespace is permitted between a command-line option and its argument.

       -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  di-
              rectory.   This  option may be specified more than once; the di-
              rectories are then searched in the order specified  (but  before
              the  current directory).  If you want to make the current direc-
              tory be read before other directories, add -I. at the  appropri-
              ate 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
