+README for Tcl configured as part of the IRAF Object Manager Library.
+
+This is the standard Tcl distribution; the only difference is the addition
+of an Imakefile to allow automated building of the Tcl library as part of
+the Object Manager.  The Imakefile should be machine independent with one
+exception, the COMPAT_OBJS definition, which lists the compatibility
+routines.  The list of objects defined here may have to be modified for
+a different host.  One way to do this is to manually run "./configure" in
+this directory to build the standard Tcl Makefile, then transfer the
+COMPAT_OBJS entry therein to the Imakefile.
+
+Tcl does not need to be installed (as in make install) to be used with the
+Object Manager.  The contents of the Tcl library are automatically included
+in libObm.a when the library is built.  The Tcl include file can be
+referenced as Tcl/tcl.h, with the OBM root directory specified as an -I
+include directory in the application's Imakefile.  In most cases the
+application using OBM need not know that Tcl is used internally.
