NEW CODE(s)
Fixed tests
Tests were not working correctly since the previous version. This is
now fixed.Fixed error messages
Many of the error messages were inconsistent or completely wrong
(due to cut-and-paste errors). They have been fixed.Fixed some return codes
The name2code and code2name functions returned 1 in the case of an
error in some situations instead of undef (which was the documented
value).Removed unnecessary dependencies
A number of modules were included as test dependencies that are only
used by the author when preparing releases. These have been removed
as dependencies. Petr Pisar on GitHub #11
