/*
** vn news reader.
**
** head.h - header line structure
**
** see copyright disclaimer / history in vn.c source file
*/

/*
** How this thing works:
**
** this structure is filled in by vns_aopen when opening an article.
** lines & hlines items will be used in providing percentage read prompts
**
** show_num & show are the article information lines presented for the user
** when the "show headers" flag is turned off.
**
** from and artid are used for mail salutations, etc.
**
** The items used for mail replies, FOLLOWING the call to the mail massager
** if there is one, are mailcmd, mail_num, and mail.  These are the items
** the massager should fill in.  If no massager exists, vns_aopen will
** fill these in directly.  If mail_err is non-null, the user won't be
** able to mail a reply to the article, and the item should be an error
** message explaining why.  If there is a mailer function, the mailcmd
** item is not used.
**
** The priv and priv_num items are for sole use of the server layer in
** the mail massager, mailer and poster functions.
**
** The postcmd, post_num, and post arguments are used in treatment of
** followups.  If post_err is non-null, followup won't be allowed, for
** the reason described therein.  If there is a poster function, the
** postcmd item isn't used.
**
** The header lines for inclusion in mail / followup files will open
** the file, and will be followed by one blank line.  The lines are literal -
** all appropriate headers should be prepended, etc.
**
** postcmd / mailcmd are used as format strings which are assumed to have a
** single %s in them some place for the placement of the users editted file.
** The result will be spawned as a command.
