# after the addition of new options, two regions of the documentation in
# isodoc.dtx need to be updated:
# 1. the body of the definition of \showkeys
# listkeys will print that body with the argument `show'
# 2. The body of the tabular (in the section `Commands'), which shows
# the options having a corresponding command.
# listkeys will print that body with the argument `defs'
#
# An easy way to replace the data in isodoc.dtx is, using the vim editor:
# 1. select the lines (the contents of \def\showkeys, say) with V and then
# 2. type :!listkeys show
