.SH DESCRIPTION
.B darcs\-monitor
reads one or more
.BR darcs (1)
repositories and sends email about every change it has not previously
sent an email about to the same address.
.
To have darcs-monitor run every time someone pushes to a repository,
add
the following lines to 
.IR _darcs/prefs/defaults .
.IP
.B apply
.B posthook
.B darcs\-monitor 
.BI \-\-charset=  charset
.B email
.I recipient
[
.B email
.I recipient
\&...
]
.br
.B apply
.B run\-posthook
.br
.PP
In the above,
.I charset
should be the MIME charset that patches
(including their metadata) are in, and
.I recipient
should be the email
address where emails should be sent.  You can specify more than one recipient
by repeating the email parameter.
.PP
You can also run
.B darcs\-monitor
from
.BR crontab (1)
or from the command line.
.
In those cases, it is easiest to specify the path to the repository on
the command line after other arguments.
.
In fact, you can specify more than one.
.PP
By default, mail is sent by calling
.IR /usr/sbin/sendmail .
Another
.B sendmail (1)
binary can be specified by using a command-line switch.
.PP
You can customise the email by providing a template.
.
You should put your own template in the file
.I _darcs/third-party/darcs-monitor/email-template
(you can use other files, but then you have to specify where it is).
.
In the template you can use the following substitutions:
.TP
.B %RECIPIENT%
the email address to which email is sent
.TP
.B %DIFF%
the Darcs-provided diff -u of the patch
.TP
.B %CHANGES%
a Darcs-provided summary of changes
.TP
.B %REPO%
the path to the repository
.TP
.B %SHORTREPO%
the final component of the path to the repository
.TP
.B %AUTHOR%
the patch author
.TP
.B %DATE%
the patch date
.TP
.B %HASH%
the patch Darcs hash
.TP
.B %TITLE%
the patch name
.TP
.B %COMMENT%
the patch comment
.PP
Also, in the template, two percent signs in sequence
.BR "" ( %% )
start a comment that extends to the end of the current line.
