    135 <p>Starting with Cupcake, individual builds are identified with a short
    136 build code, e.g. FRF85B.</p>
    137 <p>The first letter is the code name of the release family, e.g. F is
    138 Froyo.</p>
    139 <p>The second letter is a branch code that allows Google to identify
    140 the exact code branch that the build was made from, and R is by
    141 convention the primary release branch.</p>
    142 <p>The next letter and two digits are a date code. The letter counts
    143 quarters, with A being Q1 2009. Therefore, F is Q2 2010. The two
    144 digits count days within the quarter, so F85 is June 24 2010.</p>
    145 <p>Finally, the last letter identifies individual versions related to
    146 the same date code, sequentially starting with A; A is actually
    147 implicit and usually omitted for brevity.</p>
    148 <p>The date code is not guaranteed to be the exact date at which a build
    149 was made, and it is common that minor variations added to an existing
    150 build re-use the same date code as that existing build.</p>

    595 <p>There is no manifest that contains exactly those. However, there
    596 are manifests that allow building those components. The following
    597 commands work for 3.0_r1.1, and using other versions can be done by
    598 switching the git checkout paramater, and if necessary the -m parameter in
    599 repo init. The git checkout command outputs an error for the non-GPL
    600 projects, where it can't find the tag in question.</p>
