The registry package provides a general set of operations for manipulating the Windows registry. The package implements the registry Tcl command. This command is only supported on the Windows platform. KeyName is the name of a registry key. Hostname specifies the name of any valid Windows host that exports its registry.
Option indicates what to do with the registry key name.
Any unique abbreviation for option is acceptable. If the optional valueName argument is present, the specified value under keyName will be deleted from the registry. If the optional valueName is omitted, the specified key and any subkeys or values beneath it in the registry heirarchy will be deleted. If the key could not be deleted then an error is generated. If the key did not exist, the command has no effect.
