-our $PROXY_CFG = "/etc/urpmi/proxy.cfg";
+ {
+ 'medium name 1' => {
+ url => 'http://...',

-=item set_environment($env_path)
+Returns undef() in case of parsing error (and sets C<$urpm::cfg::err> to the
+appropriate error message.)
-Modifies the paths of the config files, so they will be searched
-in the $env_path directory. This is obviously to be called early.
