  - search for species (e.g., C5H8 or limonene)

  - click on "Mark"

  - goto to "Extract" in menu

    - check that "Mark List" is okay

    - click on "KPP, experimental KPP format"

    - Include inorganic reactions?       --> YES
      
    - Include generic rate coefficients? --> YES

    - click on "Extract" button

    - save file, e.g., limonene.kpp

- run conversion script, e.g.:

  ./xmcm2kpp limonene

- define the resulting *.spc and *.eqn files in a batch file, see e.g.
  limonene.bat:
  set gasspcfile = eqn/mcm/limonene.spc
  set gaseqnfile = eqn/mcm/limonene.eqn
