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:

* `LatinVerb.new("amō amāre amāvī amatum")`: create a new LatinVerb instance
* `v(latex_representation_of_macronized_string)`
* `chart(verb)`: prints a verb's chart
* `b(verb)`: 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}
