+ *
+ * Based on (at least) the following plug-ins:
+ * Screenshot
+ * GIF
+ * Randomize
+ *
+ * Any suggestions, bug-reports or patches are welcome.
+ *
+ * This plug-in interfaces to the TWAIN support library in order
+ * to capture images from TWAIN devices directly into GIMP images.
+ * The plug-in is capable of acquiring the following type of
+ * images:
+ * - B/W (1 bit images translated to grayscale B/W)
+ * - Grayscale up to 16 bits per pixel
+ * - RGB up to 16 bits per sample (24, 30, 36, etc.)
+ * - Paletted images (both Gray and RGB)
+ *
+ * Prerequisites:
+ * Should compile and run on both Win32 and Mac OS X 10.3 (possibly
+ * also on 10.2).
+ *
+ * Known problems:
+ * - Multiple image transfers will hang the plug-in. The current
+ * configuration compiles with a maximum of single image transfers.
+ * - On Mac OS X, canceling doesn't always close things out fully.
+ * - Epson TWAIN driver on Mac OS X crashes the plugin when scanning.
