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	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
	      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
