 =head1 DESCRIPTION
 
-L<Electron|https://github.com/atom/electron> is chromium-based GUI application framework. It allows you to create "native" applications in HTML, CSS, and javascript. The L<Valence> perl module is an RPC binding that lets you use perl instead of javascript for the electron "main" process. It bundles a javascript module L<valence.js|https://github.com/hoytech/valence> which is responsible for proxying messages between the browser render process(es) and your perl controller process.

 =head1 DESIGN
 
 =head2 ASYNC PROGRAMMING
 
-Like browser programming itself, programming the perl side of a Valence application is done asynchronously. The L<Valence> package depends on L<AnyEvent> for this purpose so you can use whichever event loop you prefer. See the L<AnyEvent> documentation for details on asynchronous programming.

 The C<run> method of the Valence context object simply waits on a condition variable that will never be signalled (well you can signal it if you want to, it's in C<< $valence->{cv} >>) in order to enter the event loop and "sleep forever". C<run> is mostly there so you don't need to type C<< use AnyEvent; AE::cv->recv >> in simple scripts/examples.
 
 =head2 METHODS
 
-The C<require> method initiates a C<require> call in the electron main process and immediately returns a C<Valence::Object>. Any methods that are called on this object will initiate the corresponding method calls in the electron main process and will also themselves return C<Valence::Object>s. The C<new> method is slightly special in that it will use the javascript C<new> function, but it too returns C<Valence::Object>s corresponding to the newly constructed javascript objects:

-C<Valence::Object>s are essentially perl-side references to values inside the electron main javascript process. If you destroy the last reference to one of these objects, their corresponding values will be deleted in the javascript process and eventually garbage collected.

 C<Valence::Object> has a special C<attr> method which looks up an object attribute and returns a C<Valence::Object> referring to the attribute value. For example:

 =head2 CALLBACKS
 
 Because interacting with an electron process via valence is done asynchronously, callbacks are used nearly everywhere.
 
-When a perl C<sub> is found in the arguments passed to a method, it is replaced with a stub that will be replaced with a javascript function inside the electron main process. When this javascript function is invoked, an asynchronous message will be sent to the perl process which will trigger the execution of your original C<sub>.

-Before applications can send messages from perl to javascript, the C<ipcRenderer.on()> function must have been called to handle these messages. If you try to send a message before this, it is likely that the message will be delivered to the browser before the handler has been installed so your message will be lost. Applications should have javascript send a message indicating that the communication channel is ready, after which the perl component can begin sending messages to the browser.

 As mentioned above, C<sub>s nested inside hashes or arrays will currently not properly get stubbed out (but this can be fixed if needed).
 
 Attributes should ideally be accessed via a hash reference overload instead of the C<attr> special method.

 It currently always sends a C<save> (immediately followed by a C<destroy>) even when it doesn't need the value. This is inefficient and should be fixed using C<wantarray>.
