+.TH PLOTCHANGELOG 1 "Debian Utilities" "DEBIAN" \" -*- nroff -*-
+.SH NAME
+plotchangelog \- graph Debian changelogs
+.SH SYNOPSIS
+.B plotchangelog
+.I "\fR[\fPoptions\fR]\fP changelog \fR...\fP"
+.SH "DESCRIPTION"
+.BR plotchangelog
+is a tool to aid in visualizing a Debian \fIchangelog\fR. The changelogs are
+graphed with
+.BR gnuplot (1)
+, with the X axis of the graph denoting time of release and the Y axis
+denoting the Debian version number of the package. Each individual release
+of the package is represented by a point, and the points are color coded to
+indicate who released that version of the package. The upstream version
+number of the package can also be labeled on the graph.
+.PP
+Alternatively, the Y axis can be configured to display the size of the
+changelog entry for each new version. Or it can be configured to display
+approximately how many bugs were fixed for each new version.
+.PP
+Note that if the package is a Debian-specific package, the entire package
+version will be used for the Y axis. This does not always work perfectly.
+.PP
+.SH "READING THE GRAPH"
+The general outline of a package's
+graph is typically a series of peaks, starting at 1, going up to n, and then
+returning abruptly to 1. The higher the peaks, the more releases the
+maintainer made between new upstream versions of the package. If a package
+is Debian-only, it's graph will just grow upwards without ever falling
+(although a bug in this program may cause it to fall sometimes, if the
+version number goes from say, 0.9 to say, 0.10 - this is interpreted wrong...)
+.PP
+If the graph dips below 1, someone made a NMU of the package and upgraded it
+to a new upstream version, thus setting the Debian version to 0. NMU's in
+general appear as fractional points like 1.1, 2.1, etc. A NMU can also be
+easily detected by looking at the points that represent which maintainer
+uploaded the package -- a solitary point of a different type than the points
+before and after it is typically a NMU.
+.PP
+It's also easy to tell by looking at the points when a package changes
+maintainers.
+.SH OPTIONS
+.TP
+.B \-l\fR, \fP\-\-linecount
+Instead of using the Debian version number as the Y axis, use the number of
+lines in the changelog entry for each version.  Cannot be used
+together with
+.BR \-\-bugcount .
+.TP
+.B \-b\fR, \fP\-\-bugcount
+Instead of using the Debian version number as the Y axis, use the number of
+bugs that were closed by each changelog entry. Note that this number is
+obtained by searching for "#dddd" in the changelog, and so it may be
+inaccurate.  Cannot be used together with
+.BR \-\-linecount .
+.TP
+.B \-c\fR, \fP\-\-cumulative
+When used together with either
+.B \-\-bugcount
+or
+.BR \-\-linecount ,
+graphs the cumulative count rather than the count in each individual
+changelog entry.
+.TP
+.B \-v\fR, \fP\-\-no-version
+Do not show upstream version labels. Useful if the graph gets too crowded.
+.TP
+.B \-m, \-\-no-maint
+Do not differentiate between different maintainers of the package.
+.TP
+.B \-s file\fR, \fP\-\-save=\fIfile
+Save the graph to \fIfile\fR in PostScript format instead of immediately
+displaying it.
+.TP
+.B \-u\fR, \fP\-\-urgency
+Use larger points when displaying higher-urgency package uploads.
+.TP
+.B \-\-verbose
+Output the gnuplot script that is fed into gnuplot (for debugging purposes).
+.TP
+.B \-g\fIcommands\fR, \fB\-\-gnuplot=\fIcommands
+This allows you to insert
+.BR gnuplot (1)
+commands into the gnuplot script that is used to generate the graph. The
+commands are placed after all initialization but before the final \fBplot\fR
+command. This can be used to override the default look provided by this
+program in arbitrary ways. You can also use things like
+"set terminal png color"
+to change the output file type, which is useful in conjunction with
+the \-s option.
+.TP
+.B \-\-help
+Show a usage summary.
+.TP
+.B \-\-version
+Display version, author and copyright information.
+.TP
+.B \-\-noconf\fR, \fP\-\-no-conf
+Do not read any configuration files (see below).
+.TP
+.I changelog \fR...
+The \fIchangelog\fR files to graph. If multiple files are specified they will all
+be displayed on the same graph. The files may be compressed with gzip. Any
+text in them that is not in Debian changelog format will be ignored.
+.SH "CONFIGURATION VARIABLES"
+The two configuration files \fI/etc/devscripts.conf\fR and
+\fI~/.devscripts\fR are sourced by a shell in that order to set
+configuration variables.  The \fB\-\-no\-conf\fR option can be used to
+prevent reading these files.  Environment variable settings are
+ignored when these configuration files are read.  The currently
+recognised variables are:
+.TP
+.B PLOTCHANGELOG_OPTIONS
+This is a space-separated list of options to always use, for example
+\fB\-l \-b\fP.  Do not include \fB\-g\fP or \fB\-\-gnuplot\fP among this list as it
+may be ignored; see the next variable instead.
+.TP
+.B PLOTCHANGELOG_GNUPLOT
+These are
+.B gnuplot
+commands which will be prepended to any such commands given on the
+command line.
+.SH "SEE ALSO"
