Will locate non-linear contiguous sectors based on CIM 
sector info ("I" command), and captures of CIM course
plots ("F" command, AKA zero-turn mapping).  Will also

one-way warp into them).  Supports up to 65535 sectors,
bubbles terminated by one-way outwarps, and bubbles
with multiple entrances. DOS, DPMI, Linux, OS/2, and
Win32 (console) executables plus source included.
