Reloads an operator type library from disk.
otrefresh [-r] [otl_file]
If you specify an otl_file, that library is reloaded, otherwise all libraries are reloaded.
This command will rarely be necessary for most users. Any changes made to operator definitions or operator type libraries automatically cause refreshes in the current Houdini session. You only need to run this command if an operator type library is modified outside the current Houdini session (by another user, from a shell, or from another Houdini session).
the contents of the OPlibraries files are also reloaded. This takes more time, but allows these files to be changed by external applications and have a running Houdini reflect these changes. Libraries not found in the OPlibraries files are not automatically uninstalled.
