    31 # When FIXPATH is set, let it process the file to make sure all paths are usable
       
    32 # by system native tools. The FIXPATH tool assumes arguments preceeded by an @
       
    33 # character points to a text file containing further arguments (similar to a
       
    34 # linker). It replaces any such arguments with a different temporary filename,
       
    35 # whose contents has been processed to make any paths native. To obtain a
       
    36 # properly processed compile_commands.json, FIXPATH is then made to invoke an
       
    37 # AWK script with the unprocessed json file as the only argument, prepended with
       
    38 # an @ character. The AWK script simply copies the contents of this processed
