This task provides a tutorial facility for some of the IRAF packages. The tutorial consists of a number of topics which are obtained by typing "tutor topic" where topic is one of the available topics. If no topic is given then the available topics are presented. The topic "all" presents all the topics.
This task is implemented using the help task. Therefore, modifying the help parameters dealing with the device and print format will also determine the output of tutor. The tutorial topic material is contained in the file Tutorial.hlp for each package. The database containing the directory to the tutorial files may or may not be the same as the standard help database.
