Hi Diego,
Because the linux is file case sensitive, the folder all have to begin
with uppercase, donĀ“t know why is that, because zend folders like
forms and models does not need this rule, and even can be in plural
form. So IMHO this is a bug.
This is probably a difference in implementation by the Zend Autoloader
and the Doctrine one. However, it is always good practice to assume
everything is case sensitive, rather than assume everything is
case-insensitive, since on unix-like systems virtually anything is, and
case-sensitive code will run on a case-insensitive machine, but not the
other way around.
