        <checkout branch="branches/WX_2_8_BRANCH"/>
    to checkout a branch.

    make - specify the make command.

    Usage: <make>nmake -f makefile.vc SHARED=1</make>

    Used as a child of <build> to specify the make command used by the

-->

<!--
    compile - modifiy <compile> to default to the command given by <make>

    Usage: as <compile>

    The <make> element of <build> spcecifies the make command used by all
    compile build steps in the build. If <make> is not given 'make' is used.

    The command for a particular compile build step can be further overridden
    using its <command> element:
        <compile>
            <command>myscript</command>

</xsl:template>

<!--
    Adds build steps to compile the library and the usual subdirectories.

    Usage: as <compile> with the additional attributes below.

    Usually the attributes default to suitable values, so typical usage
    is just <compile-all/>.

    <compile-all [ gui = 'true'|'false' ]
                 [ msw = 'true'|'false' ]
                 [ wx = 'true'|'false' ]

                 [ contrib = 'true'|'false' ]
                 [ tests = 'true'|'false' ] />

    gui     - if 'true' then build fully the subdirectories specified,
              otherwise only the wxBase subset of the directories are built.
    msw     - if 'true' then build the directory 'build/msw' when building the
              library instead of the root.
    wx      - build the library itself.
    samples, utils, demos, contrib, tests
            - build subdirectories.
