Welcome. 

-------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------

---------> Choice A: You want to download all models at once.
--------->           This is easy, but requires disk space.
--------->           Plus, not sure you'll be using all models...

svn co http://svn.lmd.jussieu.fr/Planeto/trunk the_name_of_my_folder

-------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------

---------> Choice B: You want to download a limited number of models.
--------->           This is quite wise indeed.
--------->           Whatever model you want, type the following commands

svn co http://svn.lmd.jussieu.fr/Planeto/trunk -N the_name_of_my_folder
cd the_name_of_my_folder
svn update DOC

---------> OK, great. Now choose the model(s) you'd like to get.

---------> LMD Mars GCM
svn update LMDZ.MARS

---------> LMD Mars Mesoscale and LES Models
svn update LMDZ.MARS MESOSCALE

---------> LMD Mars Mesoscale and LES Models with old physics only
svn update MESOSCALE

---------> LMD Titan GCM
svn update LMDZ.COMMON LMDZ.TITAN

---------> LMD Venus GCM
svn update LMDZ.COMMON LMDZ.VENUS

---------> LMD Earth GCM
svn update LMDZ.COMMON LMDZ.EARTH

---------> LMD Giant-Planets GCM
svn update LMDZ.COMMON LMDZ.GIANT

---------> LMD Generic GCM
svn update LMDZ.GENERIC

---------> PLOT utilities
svn update UTIL

---------> NOTE THAT SUBSEQUENT USE OF 'svn update' or 'svn log' or 'svn commit' ... WILL ONLY ACT ON FOLDERS YOU GOT.

-------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------

---------> Choice C: You are a developer. You want to download only one folder,
--------->           then make your modifications, commit and erase the working copy.

svn co http://svn.lmd.jussieu.fr/Planeto/trunk/[the_folder_you_d_like_to_download]

FIRST STEPS TOWARD COMPILATION
******************************

- install netcdf with the same compiler you plan to use for the GCM and keep in mind where the lib and include directories are located.

- if needed, install ioipsl:
   # ADVICE: copy the [GCMdir]/LMDZ.COMMON/ioipsl directory 
   # to [GCMdir]/ioipsl to get it out of svn
   # then go to [GCMdir]/ioipsl
   # Edit the compile_ioipsl.bash script to get the right paths for NCDF_INC and NCDF_LIB, then run it.

- choose your compilation options and paths in arch files tuned for your machine:
   LMDZ.COMMON/arch/arch-<youroptions>.[fcm/path]

- use makelmdz to compile the GCM (when you are using the common dynamical core):
   makelmdz -arch <youroptions> -d <nlon>x<nlat>x<nlev> -p <dirphy> gcm
