+%description
+virtualenv cloning script.
+
+A script for cloning a non-relocatable virtualenv.
+
+Virtualenv provides a way to make virtualenv's relocatable which could then be
+copied as we wanted. However making a virtualenv relocatable this way breaks
+the no-site-packages isolation of the virtualenv as well as other aspects that
+come with relative paths and '%{_bindir}/env' shebangs that may be undesirable.
+
+Also, the .pth and .egg-link rewriting doesn't seem to work as intended. This
+attempts to overcome these issues and provide a way to easily clone an
+existing virtualenv.
+
+It performs the following:
+
+- copies sys.argv[1] dir to sys.argv[2]
+- updates the hardcoded VIRTUAL_ENV variable in the activate script to the
+  new repo location. (--relocatable doesn't touch this)
+- updates the shebangs of the various scripts in bin to the new python if
+  they pointed to the old python. (version numbering is retained.)
+
+    it can also change '%{_bindir}/env python' shebangs to be absolute too,
+    though this functionality is not exposed at present.
+
+- checks sys.path of the cloned virtualenv and if any of the paths are from
+  the old environment it finds any .pth or .egg-link files within sys.path
+  located in the new environment and makes sure any absolute paths to the
+  old environment are updated to the new environment.
+
+- finally it double checks sys.path again and will fail if there are still
+  paths from the old environment present.
