# Pure Tcl: no C extension library, no documentation tree, no example modulefiles
# (bits sets MODULEPATH itself). The release tarball carries pre-built man pages,
# so no Sphinx is needed. configure looks for tclsh only in the system
# directories, so it is given ours. Built in a copy of the source tree.

# The installed bin/modulecmd execs modulecmd.tcl by its absolute build path,
# with the tclsh of the build. Replace it with one that locates itself, also
# through links, and runs the tclsh8.6 beside it (bits' runtime/), else the one
# on PATH (this package alone), so it works wherever it is copied.
