+---+++ HOW TO BLOCK THE CHECKS
+
+=checkDependencies()= function will do nothing if either of two conditions are met:
+
+   * Either there is =NOCPAN= file exists in =lib= subdirectory of the =rootDir=.
+   * Or FOSWIKI_NOCPAN environment variable exists.
+   
+The block is administrativly mandatory; i.e. there is no way to get around it
+until these conditions are fullfilled and there is no flag/option of suppres
+their effect.
