## VFS
### Helpers
namespace eval ::vfs::kitdll::vfsdata {}
set ::vfs::kitdll::vfsdata::fileidx -1

### Implemented
#### Single Handler
proc ::vfs::kitdll::vfshandler {hashkey subcmd args} {
	set cmd $args
	set cmd [linsert $cmd 0 "::vfs::kitdll::vfsop_${subcmd}" $hashkey]

	return [eval $cmd]
}

proc ::vfs::kitdll::chanhandler {hashkey subcmd args} {
	set cmd $args
	set cmd [linsert $cmd 0 "::vfs::kitdll::chanop_${subcmd}" $hashkey]

	return [eval $cmd]
}

#### Actual handlers




##### Finished




















































proc ::vfs::kitdll::vfsop_stat {hashkey root relative actualpath} {
	catch {
		set ret [::vfs::kitdll::data::getMetadata $hashkey $relative]
	}

	if {![info exists ret]} {
		vfs::filesystem posixerror $::vfs::posix(ENOENT)
