Help commands (TCLX)
The help facility allows one to look up help pages which
were extracted from the standard Tcl manual pages and Tcl
scripts during Tcl installation. Help files are structured
as a multilevel tree of subjects and help pages. Help
files are found by searching directories named
help in the directories listed in the
auto_path variable. All of the files in the list
of help directories form a virtual root of the help tree.
This method allows multiple applications to provide help
trees without having the files reside in the same
directory.
