This package provides the runtime core for file type recognition engines written in pure Tcl and is thus used by all other packages in this module such as fileutil::magic::filetype and the two compiler packages fileutil::magic::cgen and fileutil::magic::cfront.



All of the types above exit in an unsigned form as well. The type names are the same, with the character "u" added as prefix.
