+.SH NAME
+autopano-sift \- Automatic panorama stitching package
+.SH INTRODUCTION
+The autopano-sift package contains a number programs to ease the creation of
+panoramic images. A tedious task in panoramic image creation from many
+individual images is the aligning of the images so they fit together. This is
+normally done by using control points which give information about shared
+image features. For example, image two images of a church. Lets assume both
+images overlap so that the rooftop of the church is visible in both. By
+telling a panorama software that the roof is in both images at a specific
+position the images can be aligned. At least three control point pairs between
+every two images are required usually.
+
+The manual work of creating this control points can be immense. Especially for
+panorama images holding more than one line of images there is a huge number of
+possible overlaps.
+
+The autopano-sift package can automatically create control point pairs by
+using a combination of sophisticated algorithms and models. For most
+feature-rich images it works very well, often outperforming humans in
+coverage, precision and speed.
+
+In the following, the individual utilities are introduced. If you want a quick
+start, try the
+.BR autopanog (1)
+GUI frontend.
+
+.SH DESCRIPTION
+.B autopanog
+The GTK# GUI frontend for generating and matching SIFT keypoints. As a user
+wanting to stitch panorama images, this is all you will ever need. See
+.BR autopanog (1)
+
+.B autopano
+The keypoint matching program. It can take SIFT keypoint files as input and
+produce PTO output files. See
+.BR autopano (1)
+
+.B generatekeys
+The SIFT keypoint extraction program. Takes an image from you, and gives
+keypoints back. Optionally can downscale the image to a given resolution, so
+your memory size is cared for. See
+.BR generatekeys (1)
+
+.B showone
+Show the SIFT keypoints overlayed over the source image. Use includes
+debugging and tuning of SIFT parameters and to get an impression how well
+spread the keypoints are. See
+.BR showone (1)
+
+.B showtwo
+Do simplistic matching of SIFT keypoints between two images, without geometric
+model. Use includes representing general matching quality. Optionally filter
+only a given number of "best" keypoint matches. See
+.BR showtwo (1)
+
+.SH BUGS
+If you find any bugs in the programs, please mail the author.
