The following verbs have been made available to this session:

  * AFIRST   / AFIRST_DEP
  * ASECOND  / ASECOND_DEP
  * ATHIRD   / ATHIRD_DEP
  * ATHIRDIO / ATHIRDIO_DEP
  * AFOURTH  / AFOURTH_DEP

As well as some primary irregulars:

  * TO_BE
  * TO_CARRY
  * TO_COME

Tab-completion of the conjugation \"vectors\" is supported.

Helpful methods `chart(verb)` which prints a verb's chart as well as `b(verb)`
which prints the
`active_voice_indicative_mood_present_tense_first_person_singular_number` of
`verb`.

Verb strings can be entered using the LaTeX-style ASCII representations of
macron-bearing letters e.g.: \\={e}, \\={a}, and NB: \\={\\i}
