printf("%1$s [OPTIONS...] COMMAND ...\n"
"\n%5$sDisplay and Process Credentials.%6$s\n"
"\n%3$sCommands:%4$s\n"
- " list Show installed and available versions\n"
- " cat CREDENTIAL... Show specified credentials\n"
+ " list Show list of passed credentials\n"
+ " cat CREDENTIAL... Show contents of specified credentials\n"
" setup Generate credentials host key, if not existing yet\n"
" encrypt INPUT OUTPUT Encrypt plaintext credential file and write to\n"
" ciphertext credential file\n"
