Instructions for users

After installation, trexio-tools provides an entry point, which can be accessed via CLI:

trexio --help

This will list all currently supported command line arguments. For example,

trexio convert-from -t gamess -i data/GAMESS_CAS.log -b hdf5 trexio_cas.hdf5

converts data from the GAMESS_CAS.log output file of the GAMESS code (note also -t gamess argument) into the TREXIO file called trexio_cas.hdf5 using -b hdf5 back end of TREXIO.
