Omorfi is open source implementation of Finnish morphology. It's licenced under GNU GPL. The binary packages of omorfi contain only some of the transducers and documentation of open source morphology for Finnish language. If you need to modify or customize them you must compile from source code packages or version control system instead. Binary packages are not released as often as morphology is updated.
For full documentation see also README and doc/ directory.
Transducers and documentation of binary packages can be copied anywhere. Some
hfst-related programs may automatically search default installation locations,
such as $prefix/share/omorfi/ or $prefix/share/hfst/fi-FI/.
The most typical way to use the transducers is via command line utilities,
such as hfst-optimized-lookup or hfst-lookup. You may also access them
using the HFST library, or the HFST optimized lookup library.
