/*
 * 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.build_id
 * 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
 * home_path
 *
 *
 * 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>
