     17 #  This shell script is used to download the sources of the ccache
     18 #  tool that can be used to speed-up rebuilds of NDK binaries.
     19 #
     20 #  We use a special patched version of ccache 2.4 that works
     21 #  well on Win32 and handles the dependency generation compiler
     22 #  flags (-MMD -MP -MF) properly.
     23 #
     24 #  Beta versions of ccache 3.0 are supposed to do that as well but
     25 #  have not been checked yet.
