+# Quack 1.0 beta - Quality assurance tool for text scanning projects.
+#
+# Generates zoomable (OpenSeadragon) views of scanned text pages with overlays
+# containing OCR-text from ALTO-files. The views are static HTML pages that
+# can be viewed directly from the file system or through a webserver.
+#
+# Note that the images used for OpenSeadragon are PNG and not tiled, which
+# makes this script a very poor choice for generating pages for end-users.
+# The focus is fully on QA, there pixel-perfect reproduction is required.
+# The non-tile choice is to minimize storage space.
+#
+# The script upports iterative updates by re-using existing structures when
+# source files are added and the script is executed again. The destination
+# folder is fully self-contained and suitable for mounting under a webserver
+# with no access to the original files.
+#
+# Requirements:
+# Some unix-flavor with bash (only tested under Ubuntu)
+# GraphicsMagick (JPEG2000 -> PNG conversion is twice as fast as ImageMagick)
+# ImageMagick (to create histograms)
+# openseadragon.min.js (download at http://openseadragon.github.io/#download)
