-Buildout recipe for installing Python distutils distributions as eggs

zc.recipe.egg_/README.txt

+Buildout Egg-Installation Recipe
+================================
+
+The egg-installation recipe installes eggs into a buildout eggs
+directory.  It also generates scripts in a buildout bin directory with 
+egg paths baked into them.
+
+The recipe provides the following options:
+
+eggs
+    A list of eggs to install given as one ore more setuptools
+    requirement strings.  Each string must be given on a separate
+    line.
+
+find-links
+    One or more addresses of link servers to be searched for
+    distributions.  This is optional.  If not specified, links
+    specified in the buildout section will be used, if any.
+
+index
+    The optional address of a distribution index server.  If not
+    specified, then the option from the buildout section will be
+    used.  If not specified in the part data or in the buildout
+    section, then http://www.python.org/pypi is used.
+
+python
+    The name of a section defining the Python executable to use.
+    This defaults to buildout.
+    
+unzip
+   The value of this option must be either true or false. If the value
+   is true, then the installed egg will be unzipped. Note that this is
+   only effective when an egg is installed.  If a zipped egg already 
+   exists in the eggs directory, it will not be unzipped.
+
+To do
+-----
+
+- Some way to freeze the egg-versions used.  This includes some way to
+  record which versions were selected dynamially and then a way to
+  require that the recorded versions be used in a later run.
+
+- More control over script generation.  In particular, some way to 
+  specify data t be recored in the script.
