+/* All the text below will be used for help notes */
+DESCRIPTION START:
+
+The **LePetitSASpackage** package is an implementation
+of a little "*Hello World*" SAS package presented during
+**NJSUG** meetup.
+
+It is build for fun, but also (or foremost) to show us
+how easy it is to build SAS packages.
+
+*"I have serious reason to believe that the planet from which
+the little package came is the asteroid known as B612.
+This asteroid has only once been seen through the telescope.
+That was by a Turkish astronomer, in 1909."*
+
+---
+
+DESCRIPTION END:[NOTE] The SQLinDS package is added as a dependency just to show the it can be done. In normal circumstances, when a package doesn't have dependencies the ReqPackage: tag is skipped. The Required: tag is also just for demonstration.
Code files have to be placed in proper type-directories. And ordered accordingly. In this case teh following setup will work.
+ +/* 01_macro -> fox.sas */
+
+/* 02_formats -> rose.sas */
+
+/* 03_functions -> prince.sas */Directories structure can be easily created by ourselves with the dlcreatedir option. If the option is not available, then it can be done by hand.
