+3.3 (2015-01-22)
+ * accept input from sys.stdin if "-" is specified
+   for both dump and restore (issue #1)
+ * new normalize_py() helper to set sys.stdout to
+   binary mode on Windows
+
+3.2 (2015-07-02)
+ * hexdump is now packaged as .zip on all platforms
+   (on Linux created archive was tar.gz)
+ * .zip is executable! try `python hexdump-3.2.zip`
+ * dump() now accepts configurable separator, patch
+   by Ian Land (PR #3)
+
+3.1 (2014-10-20)
+ * implemented workaround against mysterious coding
+   issue with Python 3 (see revision 51302cf)
+ * fix Python 3 installs for systems where UTF-8 is
+   not default (Windows), thanks to George Schizas
+   (the problem was caused by reading of README.txt)
+
+3.0 (2014-09-07)
+ * remove unused int2byte() helper
+ * add dehex(text) helper to convert hex string
+   to binary data
+ * add 'size' argument to dump() helper to specify
+   length of chunks
+
+2.0 (2014-02-02)
+ * add --restore option to command line mode to get
+   binary data back from hex dump
+ * support saving test output with `--test logfile`
+ * restore() from hex strings without spaces
+ * restore() now raises TypeError if input data is
+   not string
+ * hexdump() and dumpgen() now don't return unicode
+   strings in Python 2.x when generator is requested
+
+1.0 (2013-12-30)
+ * length of address is reduced from 10 to 8
+ * hexdump() got new 'result' keyword argument, it
+   can be either 'print', 'generator' or 'return'
+ * actual dumping logic is now in new dumpgen()
+   generator function
+ * new dump(binary) function that takes binary data
+   and returns string like "66 6F 72 6D 61 74"
+ * new genchunks(mixed, size) function that chunks
+   both sequences and file like objects
+
+0.5 (2013-06-10)
+ * hexdump is now also a command line utility (no
+   restore yet)
+
+0.4 (2013-06-09)
+ * fix installation with Python 3 for non English
+   versions of Windows, thanks to George Schizas
+
+0.3 (2013-04-29)
