+STYLEGUIDE:
+
+Always do:
+
+Pragmatic modules ALWAYS to use in ALL packages: 
+
+use strict;
+use warnings;
+
+Only for packages for including package UNIVERSAL definitions
+
+use Xerl::Page::Base;
+
+Object oriented coding style
+
+Always use method prototypes if possible
+
+sub foo($;$) { .... }
+
+Explicit object typing if possible
+
+my Class::Name::Here $foo = Class::Name::Here->new();
+
+If no real ret val, set undef; explicitly
+
+sub foo() {
+  # Do some stuff
+...
+# Set explicit undef ret value
+return undef;
+}
+
+Private subs use _ as its prefix and are called only from the current package.
+
+package Xerl::Foo::Bla;
+.
+.
+
+sub _iamprivate($) {
+my Xerl::Foo:Bla $self = $_[0];
+.
+.
+}
+
+sub iampublic($) {
+my Xerl::Foo:Bla $self = $_[0];
+$self->_iamprivate();
+return undef;
+}
+
+Static subs (not OOP) are in CAPITAL letters. 
+
+sub IAMSTATIC($) {
+print shift;
+return 'Hello World';
+}
+
+sub iamdynamic($) {
+my Xerl::Foo:Bla $self = $_[0];
+return Xerl::Foo::Bla::IAMSTATIC( $self->get_somevalue() );
+}
+
+Static private subs start with _ and are written in CAPITAL letters
+
+sub _IAMSTATICPRIVATE() { 
+.
+.
+}
+
+Use Pidy to automaically restyle the code! (make perltidy)
+
+Mark things which are still to do with TODO: at any place in the source
+tree. (Can be searched for using 'make todo').
