This script is purely file based; it needs to parse the ontology each time

Subsequent parses can be speeded up using the use_cache option

.PP
writes parse errors in \s-1XML\s0 \- defaults to \s-1STDERR\s0
(there should be no parse errors in well formed files)
.PP
\fI\-p \s-1FORMAT\s0\fR
.IX Subsection "-p FORMAT"
.PP
determines which parser to use; if left unspecified, will make a guess
based on file suffix. See below for formats
.SS "\-use_cache"
.IX Subsection "-use_cache"
If this switch is specified, then caching mode is turned on.
.PP
With caching mode, the first time you parse a file, then an additional
file will be exported in a special format that is fast to parse. This
file will have the same filename as the original file, except it will
have the \*(L".cache\*(R" suffix.
.PP
The next time you parse the file, this program will automatically
check for the existence of the \*(L".cache\*(R" file. If it exists, and is
more recent than the file you specified, this is parsed instead. If it
does not exist, it is rebuilt.
