NAME
       burst - explode digests into nmh	messages

SYNOPSIS

       burst [-help] [-version]	[+folder] [msgs] [-inplace | -noinplace]
	    [-mime | -nomime] [-automime] [-quiet | -noquiet] [-verbose	|
	    -noverbose]

DESCRIPTION
       burst considers the specified messages in the named folder to be	Inter-
       net digests, and	explodes them in that folder.

       If  -inplace  is	 given,	 each digest is	replaced by its	"table of con-
       tents" and the digest is	removed.  burst	then  renumbers	 the  messages
       which follow the	digest,	in the folder, making room for each of the ex-
       ploded  messages, which are placed immediately after the	"table of con-
       tents".

       If -noinplace is	given, each digest is preserved, no table of  contents
       is  produced,  and  the	exploded messages are placed at	the end	of the
       folder.	Other messages in the folder are not affected.

       If -automime is given, burst will try to	determine if  the  message  is
       formatted  with	MIME and contains MIME parts of	type "message/rfc822".
       If it does, it will burst the message using MIME	formatting rules.  The
       -mime switch can	be used	to enforce the use of  MIME  formatting.   The
       -nomime switch will force burst to use RFC 934 rules.

       The  -quiet  switch directs burst to be silent about reporting messages
       that are	not in digest format.

       The -verbose switch directs burst to tell the user the general  actions
       that it is taking to explode the	digest.

       It  turns  out  that burst works	equally	well on	forwarded messages and
       blind-carbon-copies as on Internet digests, provided  that  the	former
       were generated by forw or send.

FILES
       $HOME/.mh_profile   The user's profile.

PROFILE	COMPONENTS
       Path:		   To determine	the user's nmh directory.
       Current-Folder:	   To find the default current folder.
       Msg-Protect:	   To set mode when creating a new message.

DEFAULTS
       +folder		   The current folder.
       msgs		   The current message.
       -noinplace
       -automime
       -noquiet
       -noverbose

CONTEXT
       If  a  folder is	given, it will become the current folder.  If -inplace
       is given, then the first	message	burst  becomes	the  current  message.
       This  leaves  the  context ready	for a show of the table	of contents of
       the digest, and a next to see the first	message	 of  the  digest.   If
       -noinplace  is  given,  then the	first message extracted	from the first
       digest burst becomes the	current	message.  This leaves the context in a
       similar,	but not	identical, state to the	context	 achieved  when	 using
       -inplace.

BUGS
       The burst program enforces a limit of approximately 1,000 on the	number
       of  messages which may be burst from a single message. There is usually
       no limit	on the number of messages which	may reside in the folder after
       the bursting.

       Although	burst uses a sophisticated algorithm to	 determine  where  one
       encapsulated  message  ends and another begins, not all digest creators
       use an encapsulation algorithm.	In degenerate cases, this usually  re-
       sults in	burst finding an encapsulation boundary	prematurely and	split-
       ting  a	single	encapsulated message into two or more messages.	 These
       erroneous digest	creators should	be fixed.

       Furthermore, any	text which appears after the last encapsulated message
       is not placed in	a separate message by burst.  This text	is usually  an
       "End of digest" string.	As a result of this possibly unfriendly	behav-
       ior  on	the part of burst, note	that when the -inplace option is used,
       this trailing information is lost.  In practice,	this is	not a  problem
       since  correspondents  usually place remarks in text prior to the first
       encapsulated message, and this information is not lost.
