// Package batch contains the non-interactive maintenence commands.

// Package batch contains both interactive and non-interactive maintenence

// commands.

//

// The interactive batch commands are as follows:

//

//   - `install` does the initial install for bulletin.  This will create

//     and seed the database and create the initial user.  It will also

//     create the user's crontab entries.

//   - `new-user` creates a new user.

//

// The non-interactive batch commands are run from the user's crontab.

//

//   - `reboot` is supposed to be run on system reboot and will delete

//     all shutdown messages.

//   - `expire` removes all expired messages and deletes broadcast messages

//     older than 3 days.

Package dclish A DCL-like command line parser.

From the OpenVMS manual on how to parse a DCL command line.

The following rules apply when entering DCL commands. Refer to

Chapter 5 for information about using extended file names in DCL

commands.

  - Use any combination of uppercase and lowercase letters. The DCL

    interpreter translates lowercase letters to uppercase. Uppercase and

    lowercase characters in parameter and qualifier values are equivalent

    unless enclosed in quotation marks (" ").

  - Separate the command name from the first parameter with at least one

    blank space or a tab.

  - Separate each additional parameter from the previous parameter or

    qualifier with at least one blank space or a tab.

  - Begin each qualifier with a slash (/). The slash serves as a separator

    and need not be preceded by blank spaces or tabs.

  - If a parameter or qualifier value includes a blank space or a tab,

    enclose the parameter or qualifier value in quotation marks.

  - You cannot specify null characters (<NUL>) on a DCL command line,

    even if you enclose the null character in quotation marks.

  - Include no more than 127 elements (parameters, qualifiers, and qualifier

    values) in each command line.

  - Each element in a command must not exceed 255 characters. The entire

    command must not exceed 1024 characters after all symbols1 and lexical

    functions2 are converted to their values.

  - You can abbreviate a command as long as the abbreviated name remains

    unique among the defined commands on a system. DCL looks only at the

    first four characters for uniqueness.
