Readme for hinotify-0.3

hinotify, a library to [inotify] which has been part of the Linux kernel
since 2.6.13.

inotify provides file system event notification, simply add a watcher to
a file or directory and get an event when it is accessed or modified.

This module is named `hinotify`.

See example code in the `examples` directory, distributed with the source



**hinotify 0.3**
:   * Compiles with GHC 6.12, GHC 6.10.4, GHC 6.8.2 and GHC 6.6.1

**hinotify 0.2**
:   * Updates to the API
        - Function names is now in semiCamelCase
        - Restructure event parameters to make it more consistent
    * Small test suit in `tests/`
    * Compiles with GHC 6.8.2 and GHC 6.6.1
    * Requires Cabal 1.2

**hinotify 0.1**
:   Initial release


The API basically consists of:

    initINotify :: IO INotify
    addWatch :: INotify
             -> [EventVariety]   -- different events to listen on
             -> FilePath         -- file/directory to watch
             -> (Event -> IO ()) -- event handler
             -> IO WatchDescriptor
    removeWatch :: INotify -> WatchDescriptor -> IO ()

A sample program:

    import System.Directory
    import System.IO

    import System.INotify

    main :: IO ()
    main = do
        inotify <- initINotify
        print inotify
        home <- getHomeDirectory
        wd <- addWatch
        print wd
        putStrLn "Listens to your home directory. Hit enter to terminate."
        removeWatch inotify wd


The code is available via the [homepage], and via darcs:

    darcs get --partial

The [API] is available online.

I'm most grateful for feedback on the API, and what else you might have to
