# check_cli_importdir.sh - verify gnomint-cli `importdir` absorbs an
# OpenSSL CA.pl-style directory layout. We bootstrap one with openssl,
# then point importdir at it and assert the CA + a sample issued cert
# both end up in the resulting database.
#
# The fixture mirrors what `CA.pl -newca` produces:
#   <root>/cacert.pem            CA self-signed cert
#   <root>/serial                next serial counter
#   <root>/private/cakey.pem     CA private key (unencrypted; we use
#                                -nodes so importdir doesn't need a
#                                passphrase fed in)
#   <root>/certs/<sha1>.pem      one issued leaf cert
#   <root>/crl/                  empty (importdir just checks for it)
