Ok, i see your point... In fact, it is not a real API of mine, the test
is here because it is in the exec "test", that you can found of unix.
Basically, i took the man of "test" and reimplement it as it is...
But i can extend it...
For example : Is_newer_than_date(x) can be a good test also.

Well perfect, what about Is_bigger_than_size(x), Is_smaller_than_size(x),
Is_equal_to_size(x) with x of type
type file_size =
TO of int
| GO of int
| MO of int
| KO of int
| O of int
And rounding to the the same unit.

I prefer not to implement directly the size field, which doesn't speak

Preference is very interesting... Because i would to have some people
using my lib ;->
The discussion is totally open, my lib is at an early stage of dev and i
would like to have suggestion ( i don't defend the actual layout of the
lib which was at first and adhoc lib for some dev of mine ).
Kind regard
