60 # FL_OBJECT *some_obj;
64 # This is detailed more closely below

67 # placing them in the hold space until the end of the struct is reached
68 # and we can ascertain the struct's name.
70 # All other lines are deleted:

79 # 1. Perform a little pretty formatting.
80 s/\(FL_OBJECT \*\)/\1 /
82 # 2. Append to the hold space and delete from the pattern space.
87 # The struct is ended by "} FD_xxx;", so now's the time to paste back the
88 # contents of the hold space.
91 # 1. Rewrite "} FD_xxx;" as "\nstruct FD_xxx : public FD_base {".

95 # 2. The hold space contains the FL_OBJECT lines, preceded by a new line.
96 # To get rid of this new line, we exchange the contents of the hold and
97 # pattern spaces, remove the new line and then exchange back.
100 # 3. Paste the contents of the hold space beneath the "struct FD_xxx" line.
101 # and empty the hold space
104 # 4. Close the struct and append an empty line.
