* The given version number is assumed to be a SemVer version number. Additionally, if the version
|
|
* has a prerelease component, it is assumed to have the format "<build type>.<build version",

* @param {string[]} platforms - A list of browsers to generate versions for.

* @param {string} version - The current version.
|

* @returns {object} An object with the browser as the key and the browser-specific version object
|
|
* as the value. For example, the version `9.6.0-beta.1` would return the object
|
|
* `{ firefox: { version: '9.6.0.beta1' }, chrome: { version: '9.6.0.1', version_name: '9.6.0-beta.1' } }`.
