 \section{Obtaining the code}
-The master version of the radiation code is held under version control (FCM)
-on the Met Office Science Repository Service (MOSRS) at
-https://code.metoffice.gov.uk/trac/socrates/wiki. Development information and
-instructions are available from this page. Releases are
-made from specific revisions of the trunk and made available 
-as a self-contained tar package.
-
-To obtain the latest version of the code or to get an account on the MOSRS
-please email the radiation code owner at the Met Office, currently
-james.manners@metoffice.gov.uk. The code is freely available under a
-BSD 3-clause licence.
-
-Once extracted, instructions for compilation may be found within the
-distribution's {\tt README} file.
-
-The code is written in Fortran 95 and has primarily been tested with the Intel 
-ifort and GNU gfortran compilers. Scripts are written in the korn or bash
-shells and it is recommended that one of these is used as the command shell.
-A local installation of the netCDF fortran libraries and modules is also
-required if the netCDF functionality is to be used.
