:obscure: adj. Used in an exaggeration of its normal meaning, to
imply total incomprehensibility. "The reason for that last crash
is obscure." "The `find(1)' command's syntax is obscure!"
The phrase `moderately obscure' implies that something could be
figured out but probably isn't worth the trouble. The construction
`obscure in the extreme' is the preferred emphatic form.
