Structure of a CPAN distribution: sample .pl files; .tar.gz for use in testing

[James E Keenan]

Two questions related to the directory structure of a distribution 
intended for CPAN:

1.  What is the current best practice for including sample Perl 5 
programs intended to illustrate usage of the module?  What directory 
should they be placed in?

2.  Is it possible to include another archive file in a CPAN 
distribution and not have it interfere with the normal operations of the 
distribution?

Example:  I have a subroutine which has to gracefully handle certain 
.tar.gz files that have a non-standard directory structure.  I want this 
tarball to be available for use in my t/*.t tests, but I don't want it 
to be decompressed when a user says 'gunzip' or 'tar' (or when 'make' 
does something).
