; 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
; # ...
