[Christian Hammers]

Package: rate-engine
Severity: serious
Usertag: transition-libmysqlclient15-dev

Dear maintainer

Please upgrade the build dependencies of your package to use
	libmysqlclient15-dev

as the other libmysqlclient packages are about to be removed from
unstable and you package will FTBFS else.
The upgrade should be without problems.

thanks,
