# 315EHVb - cnv (CoNVert number bases) <NumberString> <FromBase> <ToBase>
#   created by Pip Stuart <Pip@CPAN.Org>
#  If you only supply a number, it will convert to hex if it's decimal &&
#    decimal if it contains only valid hex digits.  If you just provide one
#    base parameter, it assumes that your number is already base10 && that
#    you've supplied the ToBase.  Otherwise, you need from && to parameters.
#  Examples:    `cnv 127   10 16` == "7F"
#               `cnv 7F    16 3`  == "11201"
#               `cnv 11201 3  7`  == "241"
#               `cnv 241   7  10` == "127"
# Eror checking is minimal.
