+The 'fiasco' subdirectory of the Netpbm source tree is primarily a copy
+of the source distribution of the Fiasco package by Ullrich Hafner.
+Bryan Henderson adapted fiasco-1.0 on July 6, 2000 to netpbm, and then
+merged in all the updates from fiasco-1.3 on February 9, 2001.
+
+The changes are:
+
+- Uses Netpbm libraries for input and output of Netpbm format images.
+
+- Works with maxvals other than 255 in Netpbm input images.  This change
+  also makes a minor correction to the maxval 255 case.  Where the Fiasco
+  package multiplies by 16 to convert from 8 bit to 12 bit intensity,
+  the correct factor is 4095/255.
+
+- Does not issue warning when system configuration file not found.
+  The location of that file is a compile-time option in 'fiasco', but
+  fixed at /etc in Netpbm.  The expectation is that Netpbm users will
+  never have a system configuration file.
+
+- Does not fail if basis file small.fco is not found.  The Fiasco code
+  already contained facilities for defaulting to a built-in version of
+  small.fco, but it was disabled by an early check for existence of
+  the basis file as an actual file.  In Netpbm, that check for
+  existence is simply removed.
+
+- Remove WINDOWS config.h configuration macro, which determined whether
+  files would be open with "b" flag (binary).  Use "b" flag unconditionally.
+
+- Rename internal "log2" function to "Log2" to avoid conflict with existing
+  "log2" macro or function.  The original package has conditional compilation
+  to allow it to use the existing log2 when configured for a system that has
+  it.  In Netpbm, we always use the private version.
+
+- Compilation warnings fixed.
+
+- 'bin' subdirectory moved to top level directory.
+
+- man pages for programs moved from doc subdirectory to top level directory.
+
+- man page of pnmpsnr created.
