       The following lists all of the namelist variables that can appear in the Buildconf/xxxconf/drv_flds_in
       files, where xxx = [cam, clm, ...]. The driver buildnml treats all of these files as user_nl_cpl files
       for generating the driver drv_flds_in file, which will appear in CaseDocs and in $RUNDIR.

      MEGAN specifier. This is in the form of: Chem-compound = megan_compound(s)
      where megan_compound(s) can be the sum of megan compounds with a "+" between them.
      In each equation, the item to the left of the equal sign is a CAM chemistry compound, the
      items to the right are compounds known to the MEGAN model (single or combinations).
      For example: megan_specifier = 'ISOP = isoprene', 'C10H16 = pinene_a + carene_3 + thujene_a'
