# The script transforms the template for each project in the following
# way:
#
#   1) Replaces the project GUID to ensure that the files are unique.
#
#   2) Updates the name of the project and the .dpr-file.
#
#   3) Updates unit references.
#      For each .pas-file in the project folder a reference will be added.
#
#   4) Updates resource script reference.
#      For each .rc-file in the project folder a reference will be added.
#
# It is assumed that the example project has the following properties:
#
#   1) The project is located two levels down from the Examples folder.
#      For example: Examples\Foo\Bar\MyProject.dpr
