DESCRIPTION
        EC is an Internet email reader and composer that can
        download incoming messages from one or more POP3 servers,
        and send mail directly to a SMTP server, or via sendmail or
        qmail if either is installed.

        EC provides options for configuring user defined mail
        folders and mail filtering by matching text patterns in
        incoming messages. The program stores the incoming messages
        in folders that you configure, or sends them directly to the
        Trash folder for deletion. With no additional configuration,
        however, EC displays incoming messages in, naturally, the
        "Incoming" folder. (EC capitalizes the first letter of
        directory names when creating folder names.) EC displays the
        number of unread and total messages in each folder on the
        "Folder" menu. Messages can be moved from folder to folder,
        including the Trash folder, so you can retrieve messages
        that you accidentally delete.

        EC permanently deletes messages stored in the Trash folder
        after a user-configurable period of time (two days is the
        default). Refer to the section, "Configuration Files,"
        below.

        EC also supports encoding and decoding of Base64 MIME
        attachments, using an external filter program included in
        the distribution package.

USING EC
        EC uses two windows for email processing: the main window
        where you can read, sort, save, or delete incoming messages,
        and a composer window where you can enter new messages and
        reply to messages in the main window.

        If you installed EC and its supporting files correctly (as
        well as Perl and the Perl/Tk library modules), typing at the
        shell prompt in an xterm:

           # ./ec

        should start up the program and display the main window with
        the Incoming mail folder. If you receive an error message
        that the program cannot connect to the POP mail server, use
        the `-v' command line switch to produce a transcript of the
        dialog with the server:

          # ./ec -v

        If EC pops up an error message, or refuses to start at all,
        or spews a bunch of Perl error messages all over the xterm,
        consult the *README* file once again. If you need assistance
        with the installation, please contact the author of the
        program. The email address is given in the section:
        "CREDITS," below.

        The functions on the menu bar should be fairly self-
        explanatory. You can view different mail folders by
        selecting them from the "Folder" menu, and move messages
        from one folder to another by selecting the destination
        folder from the "Message -> Move To" submenu. If you have
        Motif installed, you can "tear off" the menus so they are
        displayed in a separate window.

        The "File -> Browse URL" function pops up a dialog box with
        the URL under the text cursor. If you click "OK," EC opens
        the browser that is named in the .eccconfig file, and loads
        the URL. If the browser is already open or iconified, EC
        will use that browser window to view the URL. EC supports
        Netscape 4.5-4.7, Amaya 2.4, Opera 5.0, and Lynx in an
        xterm. If you select Lynx, you will probably also need to
        set the xterm option in the .ecconfig file.

        The "File -> Attachments" function opens a dialog window to
        save attachments to disk in the main window. When you select
        "File -> Attachments" from in the composer window, the
        dialog allows you to select files that will be attached to
        the outgoing message. Refer also to the section, "MIME
        Attachments," below.

        There are a number of options for quoting original messages
        when composing a reply. Refer to the .ecconfig file for
        information about these options.

        EC also uses the X clipboard, so you can cut and paste
        between windows in EC as well as other applications. If a
        program does not have "Cut," "Copy," or "Paste" menu
        options, you can select text in the original application by
        holding down the left mouse button and dragging it across
        the text to highlight it, then changing to the destination
        text window, and pressing the middle mouse button (or the
        left and right buttons simultaneously on mice with only two
        buttons).

  Sorting Messages

        You can select whether to sort messages by Date (the
        default), the sender, or the subject, either newest first or
        oldest first, by selecting the sort field from the "Options
        -> Sort by" submenu and the "Options -> Sort Order" submenu,
        or by clicking on the headings of the message listing.

  Entering Messages

        When you click on the "New" button on the function bar below
        the incoming message listing, or select "Message -> Compose
        New Message" from the menu, a window opens with a new
        message form with header lines for the addressee, the
        subject, and the name of the FCC (File Carbon Copy) file to
        save a copy of the message in. If you have a ~/.signature
        file (refer to the .ecconfig file to configure this option),
        EC will insert that at the end of the text. You can enter
        the message below the separator line.

        Clicking on the function bar's "Reply" button, or selecting
        "Message -> Reply" from the menu bar, will open a compose
        window with the address and subject of the original message
        filled in, and the message quoted in the text area. There
        are several options that determine how EC fills in reply
        addresses and quotes original messages. Again, refer to the
        .ecconfig file for information about these options.

        Each message contains header information and body text,
        separated by a boundary line:

          --- Enter the message text below this line. ---

        This line must exist for EC to process the message, but it
        is not included in the outgoing message.

        Outgoing messages require at least the valid email address
        of a recipient to be entered on the "To:" header line.

        You can use the optional fields Cc:, Bcc:, and Reply-To:,
        either by adding them manually above the separator line, or
        selecting them from the "Message -> Insert Field" menu
        selection.

        EC supports a limited form of address "unfolding," so you
        can enter more than one email address on a To:, Cc:, Reply-
        To:, or Bcc: line, separated by commas. EC will include the
        multiple addresses in the outgoing message's header or will
        process the message to route it to all recipients.

  MIME Attachments

        You can attach Base64 binary encoded MIME attachments to
        outgoing messages by selecting the "File -> Attachments..."
        menu item in the compose window, then selecting the file or
        files to attach. If you select "File -> Attachments" from
        the main window, EC will show you a list of file attachments
        for the current message, which you can then save in their
        original format.

        When attachments are selected, EC also encloses the text
        portion of the message as a MIME "text/plain" section, and
        sets the header's Content-Type: field to "multipart/mixed."
        All messages contain the required MIME-Version:, Content-
        Type:, and Content-Transfer-Encoding: headers, whether or
        not the message contains any attachments.

CONFIGURATION
  Configuration Files

        The email client uses two configuration files, .ecconfig and
        .servers. They reside in the ~/.ec directory by default,
        although you can change their names and locations by editing
        their path names in the ec and Config.pm files directly .
        The files and directory are not visible in normal directory
        listings. Use the `-a' option to ls to view them:

          # ls -a ~/.ec

        The .ecconfig file contains user-settable defaults for the
        program's operating parameters using <option> <value>
        statements on each line. The function of each setting is
        explained in the .ecconfig file's comments.

        You can also edit the .ecconfig file by selecting 'Sample
        .ecconfig File...' from the Help menu. Pressing mouse button
        3 (the right button on many systems), pops up a menu over
        the text area. where you can save your changes. You must
        exit and restart EC for the changes to take effect.

        The .servers file contains the user login name, host name,
        port and password for each POP3 and SMTP server. EC allows
        incoming mail retrieval from multiple POP3 servers, but only
        allows one SMTP server for sending outgoing mail. The format
        of each line is:

          <server-name> <port> <user-login-name> <password>

        If there is a hyphen, '`-'', in the password field, then EC
        will prompt you for the server's password when the program
        logs on to the server.

        In standard configurations, POP3 servers use port 110, and
        the single SMTP server uses port 25.

        The .servers file must have only user read-write permissions
        (0600), otherwise the program complains. The correct
        permissions can be set with the command:

          # chmod 0600 .ec/.servers

        You must be the file's owner, of course, in order to be able
        to reset the file's permissions.

        The .servers file is not editable from the Help menu.

  Mail Directories and Folders

        EC can save messages in any number of user-configurable
        "folders," or directories, and it can move messages between
        the directories with the Message -> Move To submenu. By
        default, the mail folders are subdirectories of the
        <maildir> setting.

        Assuming that a user's HOME directory is `/home/bill', the
        directories that correspond to mail folders would are:

          Option     Value      Path
          ------     -----      ----
          maildir    ~/Mail     /home/bill/Mail
          incoming   incoming   /home/bill/Mail/incoming
          trash      trash      /home/bill/Mail/trash

        The 'Incoming' and 'Trash' folders are required. These
        directories must exist before using EC. The program will not
        create them on its own.

        EC makes the first letter of folder names uppercase,
        regardless of whether the directory name starts with a
        capital or small letter.

        All other directories can be configured in the .ecconfig
        file, using the `folder' directive. You must create the
        directories before EC can move messages into them. If a
        directory doesn't exist, EC warns you and saves the message
        in the ~/Mail/incoming directory.

  Filters

        You can sort incoming mail by matching the text in an
        incoming message with a specified pattern. Each "filter"
        line in the .ecconfig file is composed of a text pattern, a
        double equals sign, and the folder the mail is to be saved
        in. The format of a filter line in the configuration file
        is:

          filter <text-pattern>==<folder-directory>

        Because the text pattern is used "raw" by Perl, you can use
        whatever metacharacters Perl recognizes (refer to the
        `perlre' man page). Pattern matches are not case sensitive,
        and the folder-directory that the pattern matches must
        exist.

        Because of Perl's pattern matching, you must quote some
        characters that are common in email addresses which Perl
        recognizes as metacharacters, by preceding them with a
        backslash. These characters include @, [, ], <, and >. Refer
        to the example filter definitions in the .ecconfig file.

  Mail Transport Agents

        In additon to an ISP's SMTP server, EC can send outgoing
        messages to sendmail or qmail, if either is installed. In
        the .ecconfig file, the `usesendmail' and `useqmail' options
        determine which program is used. If the value of either is
        non-zero, then outgoing mail is routed to the MTA;
        otherwise, the default is to send mail directly to the ISP's
        SMTP server, using the information in the ~/.ec/.servers
        file.

        In most sendmail configurations, either the local sendmail
        must be configured to relay messages, or have a "smart host"
        defined. The wcomments in the .ecconfig file describe only a
        few possible settings. Refer to the sendmail documentation
        for further information.

        If the "useqmail" option is set, make sure that you can
        execute the qmail-inject program, which is
        /var/qmail/bin/qmail-inject in qmail's default
        configuration. EC still connects directly to an ISP's POP3
        server, and uses the system UNIX mailbox, usually
        /var/spool/mail/<user>, for incoming messages.

        The qmail-inject `-f' option is not implemented. The format
        of the sender's return address can be set using environment
        variables. Refer to the qmail-inject manual page for
        information.

  Editing the Library Path Names in the Source File

        If you would like to change the path names of library files,
        use a text editor to edit the values of *$iconpath*,
        *$cfgfilename*, *$serverfilename*, and *$base64enc* at the
        beginning of the library modules they appear in.

        The `expand_path' function expands leading tildes ('~') in
        file and path names to the value of the $HOME environment
        variable, following the convention of the UNIX Bourne shell.
        Directory separators are forward slashes ('/'), so
        compatibility with non-UNIX file systems depends on the Perl
        environment to perform the path name translation.

Maintenance
  Folder Indexes

        Although EC attempts to maintain an accurate index of read
        and unread messages in each folder, it is possible, if you
        upgrade to a later version, or backup and then delete
        messages manually, that the folder indexes will not match
        the actual contents of the folder.

        In this case, you must delete the file named .index in each
        of the folders. For example, to delete the indexes in the
        Incoming and Trash folders, use these commands:

        ` # rm Mail/incoming/.index # rm Mail/trash/.index '

        If EC does not find the .index file it will, as when you
        first ran the program, pop up a warning that it is creating
        a new .index file. The messages themselves are not affected,
        but you need to select them again to prevent the program
        from showing their status as *u* for "unread."

PRINTING THE DOCUMENTATION IN DIFFERENT FORMATS
        It is possible produce this documentation in various formats
        using Perl's POD formatting utilities:

          pod2html <ec >doc.html
          pod2latex <ec >doc.tex
          pod2man <ec >doc.man
          pod2text <ec >doc.txt
          pod2usage <ec >doc.hlp

        Refer to your system's manual pages for instructions of how
        to use these utilities.
