Summarises an ontology



writes parse errors in XML - defaults to STDERR (there should be no parse errors in well formed files)


determines which parser to use; if left unspecified, will make a guess based on file suffix. See below for formats


If this switch is specified, then caching mode is turned on.

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 ``.cache'' suffix.

The next time you parse the file, this program will automatically check for the existence of the ``.cache'' 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.


One row per ontology

Each row has the following columns

input filename
total no of terms
total no of relationships
total no of paths
avg no of paths per term (p/t)
maximum no of paths for any term
ID of term with maximum no of paths
NOTE: obsolete terms are not included
