+#   <used>: <needed 1> [... <needed N>]
+#
+# means that when <used> is included, <needed 1> (... <needed N>) must
+# be included as well.
+#
+# <needed X> and <used> are of the form

+#   <class.methodOrField(signature)>

+#   <class>
+#
+# Within dependencies, variables can be used. A variable is defined as

+#
+# variables can be used on the right side of dependencies as follows:

+#  - For methods and fields, the signature is mandatory. For
+#    specification, please see the Java Virtual Machine Specification by
+#    SUN. Unlike in the spec, field signatures (types) are in brackets.
+#
+#  - Package names must be separated by '/' (and not '.'). E.g.,
+#    java/lang/Class (this is necessary, because the '.' is used to
+#    separate method or field names from classes)
+#
+#  - In case <needed> refers to a class, only the class itself will be
+#    included in the resulting binary, NOT necessarily all its methods
+#    and fields. If you want to refer to all methods and fields, you can
+#    write class.* as an abbreviation.
+#
+# -  Abbreviations for packages are also possible: my/package/* means all
+#    methods and fields of all classes in my/package.
