 =========================
 
+First make sure that the following packages are installed in your system

+  make
+  gcc
+  git-core
+  cvs (optional)
+  subversion (optional)
+
+More packages are required but usually installed by default.

+e2factory uses a unix group named ebs by default. All users of e2factory
+must belong to that group. Create the group.
+
+  groupadd ebs
+
+Be sure to add yourself to that group.

 e2factory, for historical reasons, builds and installs its own lua. 
 Make sure you download the lua-5.1.3.tar.gz package and place it in 
 the top level of the e2factory source tree prior to building. That
