+; 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
+;
+;Section "Add to path"
+;  Push $INSTDIR
+;  Call AddToPath
+;SectionEnd
+;
+;# ...
+;
+;Section "uninstall"
+;  # ...
+;  Push $INSTDIR
+;  Call un.RemoveFromPath
