## Instructions to rebuild the docs
## In general, changes to the documentation for a class' display parameters set should be handled in this file, in the details
## list above. Default values for display parameters should be set in the class' initializer method.
##
## To update just a single class:
## run
##       compareDtContent(<className>, <documentationDir>, details)
## and check the results. This should show you what is different between the current man page file and the central definitions
## It will also find things that may have been added/edited manually in the man page file, and might need backporting into the
## central definition list.
## When you are happy with the results, run
##       updateRdFile(<className>, <documentationDir>)
##       ~/Rpacks/Gviz(<documentationDir>)
##       updateLinks(<documentationDir>)
##
## To update all classes, run
##       updateDocumentation(<documentationDir>)
## Of course you should have checked all changes before using compareDtContent()
