RS 2004-02-05: package forget does not remove resources that a package has brought with it. I'm not sure whether it unloads a DLL (8.5 will have unload), but I could verify that it does not remove namespaces created by a package. Now if a package is well-behaved (i.e. creates a single namespace named like itself, in which all variables, commands, and possible child namespaces go), the cleanup could be done with
namespace delete ::pkgName
Unloading could be combined with this:
namespace eval ::pkgName {
set unload {}
trace var pkgName::unload u {unload pkgName[info sharedlib] ;#}
}Is that so?
