upgrade-registry - convert a registry from PEAR format to Pyrus format

The upgrade-registry command is used to convert a registry from the old PEAR Installer format into the new Pyrus format, and then optionally remove the old registry.

The command creates registries in Sqlite3 and XML formats in the path passed as the argument to upgrade-registry. Note that Pyrus registries are stored in the parent directory as the installed PHP files, whereas PEAR registries are stored in the same directory as the installed PHP files, so it is necessary for Pyrus to have write access to the parent directory.

--removeold

The --removeold or -r option instructs Pyrus to remove the old PEAR registry when finished upgrading.
