Hi Aitor,

auto-connect successfully sorted the available wifi signals according
to strength and finally it connected to my wifi. Hurray!

The next test, is to include more wifi interfaces files and test
whether it can select the wifi with the best signal and choose the
corresponding interfaces file. I have the feeling that it will soon be
part of netman.

Thanks for your explanation about an NxM matrix. I am qualified in
mathematics, before somebody else pops in, only square matrices can
have an inverse. Imagine having N linear equations with N unknowns:
the matrix's elements would be the variables' coefficients and the RHS
would be a column matrix with N rows and 1 column.
