// This is an example index.json file describing Hydrilla packages. As you can

// see, for storing this information Hydrilla utilizes JSON with an additional

// extension in the form of '//' comments support.

// An index.json file conveys definitions of site resources and pattern->payload

// mappings. The definitions may reference files under index.json's containing

// directory, using relative paths. This is how scripts, license texts, etc. are

// included.

// File reference always takes the form of an object with "file" property

// specifying path to the file. In certain contexts additional properties may be

// allowed or required. Unix paths (using '/' as separator) are assumed. It is

// not allowed for an index.json file to reference files outside its directory.

// Certain objects are allowed to contain a "comment" field. Although '//'

// comments can be used in index.json files, they will not be included in

// generated JSON definitions. If a comment should be included in the

// definitions served by Hydrilla API, it should be put in a "comment" field of

// the proper object.

// Unknown object properties will be ignored. This is for compatibility with

// possible future revisions of the format.

{

    // Once our index.json schema changes, this field's value will change. Our

    // software will be able to handle both current and older formats thanks to

    // this information present in every index.json file. Schemas that differ by

    // the first (major) number are always incompatible (e.g. a Hydrilla builder

    // instance released at the time of 1.2 being the most recent schema version

    // will not understand version 2.1).

    // Schemas that are backwards-compatible will have the same major number

    // and might differ by the second (minor) version number. The third (patch)

    // and subsequent numbers are being ignored right now.
