        !            33:                        almost no one will care about
        !            34: 
        !            35: 
        !            36: If you have installed a previous version of flex, delete it (after making
        !            37: backups, of course).  This will entail removing the source directory,
        !            38: /usr/include/{flexskelcom,fastskeldef,flexskeldef}.h, and
        !            39: /usr/local/lib/flex.{skel,fastskel}, if that's where you put the various
        !            40: pieces.
        !            41: 
        !            42: 
        !            43: Decide where you want to keep flex.skel (suggestion:  /usr/local/lib) and
        !            44: move it there.  Edit "Makefile" and change the definition of SKELETON_FILE
        !            45: to reflect the full pathname of flex.skel.
        !            46: 
        !            47: Read the "Porting considerations" note in the Makefile and make
        !            48: the necessary changes.
        !            49: 
        !            50: 
        !            51: To make flex for the first time, use:
        !            52: 
        !            53:     make first_flex
        !            54: 
        !            55: which uses the pre-generated copy of the flex scanner (the scanner
        !            56: itself is written using flex).
        !            57: 
        !            58: Assuming it builds successfully, you can test it using
        !            59: 
        !            60:     make test
        !            61: 
        !            62: The "diff" should not show any differences.
        !            63: 
        !            64: If you're feeling adventurous, rebuild scan.c using various
        !            65: combinations of FLEX_FLAGS, each time trying "make test" when
        !            66: you're done.  To rebuild it, do
        !            67: 
        !            68:        rm scan.c
        !            69:        make FLEX_FLAGS="..."
        !            70: 
        !            71: where "..." is one of:
        !            72:
