+verification of downloads. Checks first for the environment variable
+C<TEXLIVE_GNUPG>, then for C<gpg>, and finally for C<gpg2>.
+Further adaption of the invocation of C<gpg> can be done using the
+two enviroment variables C<TL_GNUPGHOME>, which is passed to
+C<gpg> with C<--homedir>, and C<TL_GNUPGARGS>, which replaces the
