AC_ARG_WITH(tcl,	--with-tcl=path	specify a pathname for tcl, d=$withval, d="")

AC_ARG_WITH(tcl-ver, --with-tcl-ver=path specify the version of tcl/tk, TCL_VERS=$withval, TCL_VERS=8.0.4)

dnl Truncate anything beyond and including the second decimal point

TCL_HI_VERS=`echo $TCL_VERS | sed 's/^\([[0-9]]*\)\.\([[0-9]]*\)\.\([[0-9]]*\)/\1.\2/'`
TCL_MAJOR_VERS=`echo $TCL_VERS | sed 's/^\([[0-9]]*\)\.\([[0-9]]*\)\.\([[0-9]]*\)/\1/'`
TCL_ALT_VERS=`echo $TCL_HI_VERS | sed 's/\.//'`

dnl work with one version in the past
TCL_OLD_VERS=7.6
TCL_OLD_ALT_VERS=`echo $TCL_OLD_VERS | sed 's/\.//'`

dnl These paths are pretty hellish and should probably be pruned.
