dirwatcher

Recursively watch a directory for modifications.

Uses findit to walk the directory tree,
filewatcher to watch each dir
and minimatch to match the files.

This method is very resource-friendly for large numbers of files since only
one file handle per directory is used.

Usage

Pass a the path of a dir to watch:

``js
var dirwatcher = require('dirwatcher');

w = dirwatcher(dir, opts);
w.on('changed', function(file, stat) {
console.log(file, stat.mtime);
});
`

Events

A dirwatcher emits the following events:

* ready - when the inital directory scan is completed.
* added - when a file is added.
* changed - when the mtime of a file modified. Does not take the actual file content into account.
* removed - when a file has been removed.
* steady - 10 ms after the last event was fired.

Options

You can specify a RegExp, String (a glob pattern) or function to control which
files are inclued and which sub-directories should be skipped.

`js
w = dirwatcher(dir, {
include: '*.js',
skip: 'node_modules'
});
`

If you just want to specify the include option you can pass it as 2nd argument:

`js
w = dirwatcher(dir, '*.js');
`

__Note__: If no include option is given, the following default implementation is used:

`js
function filesOnly(f, stat) {
return stat.isFile();
}
``

Regular expressions and glob patterns are tested against a file's basename. If
you need to take the full path into account you have to pass a function instead.
