Monomotapa:
a city whose inhabitants are bounded by deep feelings of friendship,
so that they intuit one another's most secret needs and desire.
For instance, if one dreams that his friend is sad, the friend will
perceive the distress and rush to the sleepers rescue.
(Jean de La Fontaine, *Fables choisies, mises en vers*, VIII:11 Paris,
2nd ed., 1678-9)
cited in :
Alberto Manguel and Gianni Guadalupi, *The Dictionary of Imaginary Places*,
Bloomsbury, London, 1999.
A micro cms written using the Flask microframework, orignally to manage my
personal site. It is designed so that publishing a page requires no more than
dropping a markdown page in the appropriate directory (though you need to edit
a json file if you want it to appear in the top navigation).
It can also display its own source code and run its own unit tests.
The name 'monomotapa' was chosen more or less at random (it shares an initial
with me) as I didn't want to name it after the site and be typing import
paulmunday, or something similar, as that would be strange.
