Units-filter is a basic standalone filter written in C language,
flex and bison. It inputs strings like "1.5e3 µN.m.s^-1" (it could
be the time growth ratio of a torque) and outputs the value in
standard SI unit, followed by the physical dimension of this value.

example :~/src$ echo 1.5e3 µN.m.s^-1 | units-filter
0.0015   2   1  -3   0   0   0   0
example :~/src$

                                2     -3
which means : 0.0015 (SI unit) m .kg.s

When the input is not successfully parsed, the filter fails with
the exit code 1.

This filter can be embedded in educational test systems, in order to
analyze a student's answer to a problem of physics or chemistry.
