+## @Synopsis Set of functions for dealing with the problem of having to
+## @Synopsis use different version of the gcc compilers.
+##
+## The basic usage is as follows:
+## <pre>
+## - If a spell works with the latest version of gcc, do nothing.
+## - To change the compiler version for a spell, add a GCC_VERSION field
+##   to the spells DETAILS specifying major.minor version of gcc it needs,
+##   e.g. GCC_VERSION=3.4
+## - add a 'depends  gccXX' to the spell where XX == majorminor,
+##   e.g. 'depends  gcc34'
+## - add 'invoke_gcc' to the top of PRE_BUILD if the spell has a
+##   custom PRE_BUILD file
+## </pre>
+##
+## @Implementation These functions were added to allow the use of
+## @Implementation several versions of gcc in parallel.
