+.Sh NAME
+.Nm bugfiler
+.Nd file bug reports in folders automatically
+.Sh SYNOPSIS
+.Nm bugfiler
+.Op Fl ar
+.Op Fl v Ar version
+.Sh DESCRIPTION
+.Nm Bugfiler
+is a program to automatically intercept, acknowledge,
+redistribute and store bug reports.
+.Nm Bugfiler
+is normally invoked
+by the mail delivery program with a line similar to the following in
+.Pa /etc/aliases .
+.Bd -literal -offset indent
+bugs:	"|bugfiler"
+.Ed
+.Pp
+It should be noted that the login
+.Dq bugs
+must exist for the bugfiler
+to run.  Unless otherwise noted all paths used by
+.Nm bugfiler
+are
+relative to the home directory of this login.
+.Nm Bugfiler
+also
+expects all of its files and directories to be owned by
+.Dq bugs .
+.Pp
+Available options.
+.Bl -tag -width Ds
+.It Fl a
+Do not send automatic mail acknowledgement to the bug report filer.
+(The default is to send the acknowledgement with the file
+.Pa ~bugs/version/bug:ack
+appended).
+.It Fl r
+Do not redistribute.
+.It Fl v Ar version
+Override the
+.Ar version
+provided within the bug report itself.
+.El
+.Pp
+For the bug report to be correctly filed, it must contain a line
+in the following format:
+.Pp
+.Bd -filled -offset indent -compact
+.Bl -column Index folder
+.It Index: Ta Em folder Ta Ar version
+.El
+.Ed
+.Pp
+The directories
+.Pa ~bugs/ Ns Ar version
+and
+.Pa ~bugs/ Ns Ar version/ Ns Em folder
+must exist before
+.Nm bugfiler
+attempts to store the bug report.  Bug
+reports will be stored in files named by the concatenation of
+.Ar version ,
+.Em folder ,
+and sequential numbers, i.e. if
+.Ar version
+is
+.Dq 4.3 Tn BSD
+and
+.Em folder
+is
+.Dq ucb
+the first bug report will be placed in
+.Pa ~bugs/4.3BSD/ucb/1 .
+If
+.Em folder
+contains more than one component only
+the first one will be used, e.g. if
+.Em folder
+is
+.Dq bin/from.c
+or
+.Dq bin/adb/con.c
+it will be treated as if it were simply
+.Dq bin .
+.Pp
+.Pp
+If the
+.Fl r
+flag is not supplied, redistribution of the bug reports
+is done as specified in the file
+.Pa ~bugs/version/bug:redist .
+This file
+is in the format of the
+.Xr aliases 5
+file, including comments and
+entries requiring multiple lines, with the single exception that the
+.Em folder
+component of the
+.Dq Index:
+line replaces the name to alias.
+The special folder
+.Dq all:
+receives a redistribution of all bug reports
+sent to this
+.Ar version .
+For example, the
+.Pa bug:redist
+file
+.Pp
+.Bd -literal -offset indent -compact
+#	bigbug gets a copy of everything
+all:	bigbug
+#	ucb folder redistribution list
+ucb:	karels, kjd@coke.berkeley.edu
+	ra@beno.css.gov
+.Ed
+.Pp
+will send copies of all bug reports with
+.Dq ucb
+as the
+.Em folder
+to bigbug, karels, kjd, and ra.
+.Pp
+Reports that cannot be filed, due to an invalid
+.Dq Index:
+line or
+some other error, are placed in the directory
+.Pa ~bugs/errors .
+The
+.Nm bugfiler
+maintainer should correct these bug reports and then
+run
+.Nm bugfiler ,
+with the corrected report as its standard input,
+as bug reports with errors are neither acknowledged or redistributed.
+All reports that
+.Nm bugfiler
+handles are logged in
+.Pa ~bugs/log.
+.Pp
+Valid bugs are also logged in the file
+.Pa ~bugs/version/summary.
+This file has an entry for each bug report for
+.Ar version
+in the
+format:
+.Pp
+.Bd -literal -offset indent -compact
+Filename	Date
+     Subject:
+     Index:
+     Owner:	Bugs Bunny
+     Status:	Received
+.Ed
+.Pp
+.Li Filename
+is the concatenation of
+.Ar version ,
+.Em folder ,
+and a number
+as described above.
+.Xr Date
+is the date as reported by the system
+clock, using
+.Xr ctime 3 .
+The
+.Li Subject:
+and
+.Li Index:
+lines are
+copies of the
+.Dq Subject:
+and
+.Dq index:
+lines contained in the bug
+report.  The
+.Li Owner
+and
+.Li Status
+fields are intended to provide a
+rudimentary method of tracking the status of bug reports.
+.Pp
+The file
+.Pa ~bugs/bug:lock
+is the focus of all locking for
+.Nm bugfiler .
+If you wish to manipulate any of the log or error files, rename or remove
+it and
+.Nm bugfiler
+will treat all bug reports that it receives as if
+they were incorrectly formatted, i.e. it will place them in the directory
+.Pa ~bugs/errors ,
+for later recovery by the
+.Nm bugfiler
+maintainer.
+Obviously, this file must be created when you first install
+.Nm bugfiler .
+.Pp
+All errors that occur before
+.Pa ~bugs/log
+is found are logged into the system
+log file, using
+.Xr syslog 8 .
+.Sh FILES
+.Bl -tag -width /usr/share/misc/bugformatxx -compact
+.It Pa ~bugs/bug:ack
+the acknowledgement message
+.It Pa ~bugs/bug:redist
+the redistribution list
+.It Pa ~bugs/bug:lock

+.It Pa ~bugs/folder/summary
+the summary files
+.It Pa /usr/sbin/sendmail
+the mail delivery program
+.It Pa /usr/share/misc/bugformat
+a sample bug report format
+.El
+.Sh SEE ALSO
+.Xr sendbug 1 ,
+.Xr aliases 5 ,
+.Xr syslog 8
+.Sh BUGS
+Since mail can be forwarded in a number of different ways,
+.Nm bugfiler
+does not recognize forwarded mail and will acknowledge to the forwarder
+instead of the original sender unless there is a
+.Dq Reply-To
+field in the
+header.
+.Pp
+This version of
+.Nm bugfiler
+is not compatible with the version
+released with
+.Bx 4.3
+in that it doesn't complain to the sender about
+incorrectly formatted bug reports.
+Frankly, we got tired of the profanity, not to mention the extended
+conversations
+.Nm bugfiler
+was holding with
+.Xr vacation 1 .
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.2 .

+Index: folder 4.4BSD-alpha
+
+Description:
+	Detailed description of the problem, suggestion, or complaint.
+Repeat-By:
+	Describe the sequence of events that causes the problem
+	to occur.
+Fix:
+	Description of how to fix the problem.  If you don't know a

+
+-------- Remove this line and what's below it, for reference only. --------
+
+To ensure that your bug report is handled correctly by bugfiler(8),
+you must replace "folder" (on the line above starting with "Index:")
+with one of the following values:
+
+	folder  ::= bin | doc | etc | games | ideas | include | lib
+			| local | man | misc | new | sys | ucb
+			| usr.bin | usr.lib
+
+If you're not running 4.3BSD, you should also replace "4.3BSD" on
+the same line with one of the following values.
+
+	version ::= 4.3BSD | 4.3BSD-tahoe | 4.3BSD-reno | net2
+			   | 4.4BSD-alpha
+
+For example, if your bug concerns the program "/usr/bin/file" and
+you're currently running 4.3BSD-Reno, you should replace "folder"
+with "usr.bin/file", and "4.4BSD-alpha" with "4.3BSD-Reno".  The folder
+"ideas" is for suggestions.
