# BootPrefix.js
|
|
# <module definitions>
|
|
# Boot.js
|

See Boot.js for further details of the boot process.

Information about each module is kept in an object with these members:

moduleType: type of module
|

definition: object, function or string defining the module; see below
|
|
exports: exports of the module, filled in after execution
|
|
|

The `definition` can be of several types:
|
|
|
|
* An object can be used to directly specify the exports of the module
|
|
* A function with the arguments `module,require,exports` that returns `exports`
|
|
* A string function body with the same arguments
|
|
|

Each moduleInfo object is stored in two hashmaps: $tw.modules.titles and $tw.modules.types. The first is indexed by title and the second is indexed by type and then title
