I'm still debating between 2 methods:
a) Library commands must detect if the data exists (by using IFERR with LIBRCL) and either recreate with LIBSTO or at least provide a default value.
b) Use a $HANDLER program that will be called on installation, removal and have it recreate the variables.

I can think of refinements for both of these, though I'm not sure how practical they are to code:

a) Have LIBRCL take two arguments instead of one. The second one is a default value - if the recall fails, the default gets both returned and LIBSTO'd.

b) Instead of, or in addition to, $HANDLER, there is $DEFAULTS. This is a simple list of names and content, which are to be stored into the directory when the library is attached. There might also be a command LIBDEF which would restore the directory to the default values in case things get borked up.

I personally think that either version of b) is more elegant, provided there's a way to re-run the $HANDLER or restore the $DEFAULTS. Otherwise, programmers will effectively have to implement a) anyway.
