Create an operator type library from separate files.
otcollapse otl_file source_dir
This command rebuilds an operator type library file from the specified directory. The directory must contain an index file with a list of files on disk to include in the operator type library.
The index file and disk files can be created from an existing operator type library using the otexpand command.
The combination of otexpand and otcollapse lets you extract component files from an OTL with otexpand, edit them, then rebuild the OTL with otcollapse.
The command takes two arguments: the otl_file to create, and the source_dir containing the index and component files.
