+; Modify the user's PATH variable.
+;
+; Modified by JY to have both a RemoveFromPath
+; and an un.RemoveFromPath which are basically
+; copies of each other. Why does NSIS demand
+; this nonsense?
+;
+; Modified Feb 14, 2005 by Mathias Sundman:
+; Added code to remove the semicolon at the end of the path
+; when uninstalling.
+;
+; Added code to make sure we don't insert an extra semicolon
+; before our path if there already exist one at the end of
+; the original path.
+;
+; Removed duplicated "un. and install" functions and made
+; macros to duplicate the code instead.
+
+; example usage

+; Push $INSTDIR
