+If you do not plan to mess with the source, you make create a binary python package.
+This is not exactly a binary, it is a zip archive containing compiled python bytecode,
+which is quite compact. To do so, go to the scripts directory:
+
+$ cd scripts
+
+and run
+
+$ ./make_pkg
+
+This will create in the parent directory two executables, 'callirhoe' and 'calmagick'.
+Now copy them to your binary path. And you can remove the source dir, as it is no longer
+needed. You might want to copy the holiday data files first, if you want to use them
+(callirhoe takes a full path to them, so you can store them wherever you want).
+
+On a linux system, you will additionally see a Makefile created, which you can alternatively
+run with 'make install' to install the files in the standard places, 
+instead of manually copying them.

 You can get the PKGBUILD either from SVN or compressed archive or from AUR.
