+# This script is deprecated.  It used to be required by VR Studio
+# users who were using the ctattach tools to de-Cygwinify the
+# directories named in the PYTHONPATH variable after the ctattach
+# tools filled it with Cygwin-style directories, but this is no longer
+# necessary (the ctattach tools no longer touch PYTHONPATH).  In any
+# case, it was never needed outside the VR Studio.
+#
+# It also de-cygwinified each of the directories named by the the
+# $DTOOL, $PANDA, $DIRECT, etc. environment variables that ctattach
+# filled in.  This might still be useful, but it's not clear (since we
+# have the runPythonEmacs that does that instead).  For now, I've
+# taken this behavior out of the script, and we'll see if anyone
+# complains.
+#
+# This means that the only thing this script does nowadays is
+# immediately launch Python.  It could be set up to launch the
+# particular version of Python for which Panda has been built, but at
+# the moment we don't really know that (it would have to be specified
+# in the Config.pp file, and it's not, at least not completely).
