Abstract:
Example, how to setup the codetools, load a pascal unit and
extend the include path of a directory.

'Example template for current working directory','',Directory,da_Directory);
// Example 1:
// Add a sub template to extend the include search path #IncPath
// only for the current directory, not its sub directories.
// Note: 'myincludes' is a relative path, so it won't work for sub directories.

// Example 2:

// with an absolute path for the current directory and all its sub directories.
