libconfig-jfdi-perl 0.065-2 (i386 binary) in ubuntu focal

 Config::JFDI scans a directory for files matching a certain name. If such a
 file is found, and it matches an extension that Config::Any can read, then
 the configuration from that file will be loaded. It also looks for special
 files that end with a "_local" suffix, which take precedence over any other
 configuration files. The precedence takes place by merging the local config
 with the standard file using Hash::Merge::Simple (libhash-merge-simple-perl).
 .
 Essentially, this is an implementation of Catalyst::Plugin::ConfigLoader that
 exists outside of Catalyst.
