For all those who are interested in the inner workings of pkgsrc, there

is a new target "show-all" that fits to the existing "debug",
"show-tools", "show-vars" targets. It prints a list of the variables
that make up the public interface to pkgsrc. Running this target is
especially useful if you want to do some things, you know that they must
have been implemented but you don't know what it is called. It also
shows the "class" of a variable (user-defined, package-defined,
system-defined).
