# Validates package names and resolves those that don't specify categories.
#
# Given a list of words of the form "category/pkgname" or "pkgname", ensures
# that those packages exist and prints the name of all valid packages.  For
# words of the form "pkgname", the output will be the corresponding
# "category/pkgname" for the entry.
#
# \param pkgsrcdir Path to the pkgsrc tree.
# \param ... Package names to expand.
#
# \return 0 if all packages exist; 1 otherwise.  Any non-existent packages
# are logged to stderr as a warning.
