 ecKit is a cross-platform c++ toolkit that supports development of tools and
 applications at ECMWF. It is based on code developed over the last 20 years
 within the MARS software and was re-factored out to be reused by other
 applications. The main focus is UNIX/POSIX systems, and it has been thoroughly
 tested on AIX, Linux and Mac OSX. Historically, the code base pre-dates and in
 some way can be seen as a leaner substitute for some 'Boost' libraries.
