# This test is for package reexports
#   1. install p
#   2. install q (reexporting p modules)
#   3. install r (reexporting p and q modules)
#   4. configure and build s, using modules from q and r
#
# Here are the permutations we test for:
#   - Package qualifier? (YES/NO)
#   - Where is module? (defined in SELF /
#         (ORIGinally defined/REEXported) in DEPendency)
#         For deps, could be BOTH, if there is NO package qualifier
#   - Renamed? (YES/NO)
#   - Multiple modules with same name? (YES/NO)
#
# It's illegal for the module to be defined in SELF without renaming, or
# for a package to cause a conflict with itself.  A reexport which does
# not rename definitionally "conflicts" with the original package's definition.
#
# Probably the trickiest bits are when we automatically pick out which package
# when the package qualifier is missing, and handling whether or not modules
# should be exposed or hidden.
