Glad to hear it.  Note that a C interface also exists.

The installed file is "$(prefix)/etc/udunits.dat", where "$(prefix)"
is the installation-point of the package specified when the package's
"configure" script was executed.  By default, it is the parent
directory of the top-level source-directory of the package.  So, for
example, if the source of the package is "/usr/local/udunits/src", then
the data-file would be "/usr/local/udunits/etc/udunits.dat".  Otherwise,
"$(prefix)" is the value given to the "--prefix" option of the "configure"
