 To solve the issue of phase 1 mentioned earlier, a new parser has been developed that is based on

+the flex and bison tools. The following text uses DHCPv6 as an example, but the same principle
 applies to DHCPv4 and D2; CA will likely to follow. The new parser consists of two core elements
 with a wrapper around them.  The following descriptions are slightly oversimplified in order to
 convey the intent; a more detailed description is available in subsequent sections.

-Strictly speaking, the comment "make parser" is not necessary. If you updated the .ll or .yy file,
-the regular "make" command should pick those changes up. However, since one source file generates
-multiple output files and you are likely to be using a multi-process build (by specifying the "-j"
-switch on the "make" command), there may be odd side effects: explicitly rebuilding the files
-manually by using "make parser" avoids any trouble.

 One problem brought on by use of flex/bison is tool version dependency. If one developer uses
 version A of those tools and another developer uses B, the files generated by the different version
 may be significantly different. This causes all sorts of problems, e.g.  coverity/cpp-check issues
