When the environment variable '''TCL_LIBRARY'''
is defined, [Tcl]'s default initialization sequence
takes its value to be a file system directory in
which the '''init.tcl''' file should be sought first.
In a proper [Tcl] installation, use of this environment
variable should not be needed.  The main use for it
is in [Tcl]'s own build and test procedures to direct
initialization of a freshly built [Tcl] program so that
it can be tested before it is installed.  Other than
that, it should be considered a tool for "last-resort"
workarounds of broken installations, not a tool for
routine use.
----
If what you are trying to do is set an ''environment variable'' to point to directories
containing other [Tcl] [package]s, check [TCLLIBPATH].

Neither TCL_LIBRARY nor TCLLIBPATH are considered by [tclkit], though.
