  27  * This file defines build profiles for the JIB tool and others.
  28  *
  29  * A build profile defines a set of configuration options and external
  30  * dependencies that we for some reason or other care about specifically.
  31  * Typically, build profiles are defined for the build configurations we
  32  * build regularly.
  33  *
  34  * Contract against this file from the tools that use it, is to provide
  35  * a function on the form:
  36  *
  37  * getJibProfiles(input)
  38  *
  39  * which returns an object graph describing the profiles and their
  40  * dependencies. The name of the function is based on the name of this
  41  * file, minus the extension and the '-', camel cased and prefixed with
  42  * 'get'.
  43  *
  44  *
  45  * The parameter 'input' is an object that optionally contains  some data.
  46  * Optionally because a tool may read the configuration for different purposes.
  47  * To initially get a list of available profiles, the active profile may not
  48  * yet be known for instance.
  49  *
  50  * Data that may be set on the input object:
  51  *
  52  * input.profile = <name of active profile>
  53  *
  54  * If the active profile is set, the following data from it must also
  55  * be provided:
  56  *
  57  * input.profile
  58  * input.build_id
  59  * input.target_os
  60  * input.target_cpu
  61  * input.build_os
  62  * input.build_cpu
  63  * input.target_platform
  64  * input.build_platform
  65  * // The build_osenv_* variables describe the unix layer on Windows systems,
  66  * // i.e. Cygwin, which may also be 32 or 64 bit.
  67  * input.build_osenv
  68  * input.build_osenv_cpu
  69  * input.build_osenv_platform
  70  *
  71  * For more complex nested attributes, there is a method "get":
  72  *
  73  * input.get("<dependency>", "<attribute>")
  74  *
  75  * Valid attributes are:
  76  * install_path
  77  * download_path
  78  * download_dir
  79  * home_path
  80  *
  81  *
  82  * The output data generated by this configuration file has the following
  83  * format:
  84  *
  85  * data: {
