- prepare for providing nx as a tcl module (.tm file). this is just a preparation, since for testing, one cannot set up a path that prefers a local copy over a global installed one (the global tcl-site is preferred over the one specified in e.g. TCL8_5_TM_PATH)
Make library/pkgIndex.tcl traversing three directory levels (instead of just 2). This is necessary to catch the packages and library/xotcl/library. As a symptom, xocomm.test failed. This was because it was picking up comm packages in the install, rather than the source tree which did not reflect the changes in the nested object dispatches: [my connection foo] -> [[self]::connection foo]
