/*

 * This file defines build profiles for the JIB tool and others.

 *

 * A build profile defines a set of configuration options and external

 * dependencies that we for some reason or other care about specifically.

 * Typically, build profiles are defined for the build configurations we

 * build regularly.

 *

 * Contract against this file from the tools that use it, is to provide

 * a function on the form:

 *

 * getJibProfiles(input)

 *

 * which returns an object graph describing the profiles and their

 * dependencies. The name of the function is based on the name of this

 * file, minus the extension and the '-', camel cased and prefixed with

 * 'get'.

 *

 *

 * The parameter 'input' is an object that optionally contains  some data.

 * Optionally because a tool may read the configuration for different purposes.

 * To initially get a list of available profiles, the active profile may not

 * yet be known for instance.

 *

 * Data that may be set on the input object:

 *

 * input.profile = <name of active profile>

 *

 * If the active profile is set, the following data from it must also

 * be provided:

 *

 * input.profile

 * input.target_os

 * input.target_cpu

 * input.build_os

 * input.build_cpu

 * input.target_platform

 * input.build_platform

 * // The build_osenv_* variables describe the unix layer on Windows systems,

 * // i.e. Cygwin, which may also be 32 or 64 bit.

 * input.build_osenv

 * input.build_osenv_cpu

 * input.build_osenv_platform

 *

 * For more complex nested attributes, there is a method "get":

 *

 * input.get("<dependency>", "<attribute>")

 *

 * Valid attributes are:

 * install_path

 * download_path

 * download_dir

 *

 *

 * The output data generated by this configuration file has the following

 * format:

 *

 * data: {

 *   // Identifies the version of this format to the tool reading it

 *   format_version: "1.0",

 *

 *   // Name of base outputdir. JIB assumes the actual output dir is formed

 *   // by adding the configuration name: <output_basedir>/<config-name>

 *   output_basedir: "build",

 *   // Configure argument to use to specify configuration name

 *   configuration_configure_arg:

 *   // Make argument to use to specify configuration name

 *   configuration_make_arg:

 *
