soelim - interpret .so requests in groff input
soelim [ -Crtv ] [ -Idir ] [ 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
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.
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
-Idir This option may be used to specify a directory to search for
files (both those on the command line and those named in .so
requests). The current directory is always searched first.
This option may be specified more than once, the directories
will be searched in the order specified. No directory search is
performed for files specified using an absolute path.
-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:
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
