.SH DESCRIPTION
Displays a given file anywhere on your X11 root window with a transparent
background. It was made because I'm very lazy and this was easier than
making a new rxvt pixmap each time I changed my background to simulate
that transparent effect. A null desc (example: "/var/log/messages,red,")
will prevent the printing of a description and the []'s.
.PP
.SS General Options
.TP
.BI \--color " COLOR"
Use color $color as default.
.TP
.BI "\--font \|| -fn" " FONTSPEC"
Use font FONTSPEC. This can be either a fixed width font like \fB-fn\fI
fixed\fR or any font using \fB-fn \fR'\fI-*-*-*-*-*-*-*-*-*-*-*-*-*-*\fR' with
the appropriate fields filled out (see xfontsel).
.TP
.B -f \|| \--fork
Forks to the background and writes the PID of the daemon process to
standard output (useful if root-tail is being called from a script or
frontend).
.TP
.B \--reverse
Display the files in reverse order, with the newest lines at the top.
.TP
.B \--whole
Only display whole lines. If the last line of a file doesn't yet end
with a newline character then wait until it does before displaying
it. This is the default if more than one file is being displayed.
.TP
.B \--partial
This is the opposite of the \fB--whole\fR option (see above). It displays
lines even if they don't yet have a newline at the end. This is the
default if only one file is being displayed.
.TP
.B \--update
Update partial lines 'in place' if they are still on the screen when
they are updated in their files. Using \fB--update\fR automatically turns on
\fB--partial\fR.
.TP
.BI \--cont " STRING"
When partial lines are broken into two lines in the display, prefix
the 2nd line with STRING. Defaults to "\fI[+]\fR". Specify the "\fB--whole\fR"
argument to ensure partial lines are never displayed, or specify "\fB--update\fR"
to attempt to "repair" broken lines in-place.
.TP
.B \--wordwrap
The default behaviour is to fit as much as possible onto each line of
output, even if this means splitting a word between one line and the
next. The \fB--wordwrap\fR argument splits lines at spaces if
possible.
.TP
.BI \--reload " SEC COMMAND"
Re-display the file(s) and run COMMAND every SEC seconds. The
default is to never re-display the file(s).
.TP
.B \--shade
Add black shading to the font.
.TP
.B \--outline
Add a black outline to the font (making redraws quite a bit slower).
.TP
.B \--noflicker
Use slower but flicker-free update.
.TP
.B \--noinitial
Don't display the end of the file(s) initially.
.TP
.BI "\-id" " ID"
Use the given window ID for output instead of the root window.
.TP
.BI "\-i \|| \--interval" " SECONDS"
Use the specified sleeping interval between checks instead of the
default 2.4 seconds. Fractional values are OK.
.TP
.B \-V
Print version information.
.TP
.B \--frame
Surround the selected area with a frame. This is just a debugging tool
and doesn't always work properly. Use it to find the perfect geometry.

.SH EXAMPLE
.PP
root-tail -g 800x250+100+50 /var/log/messages,green /var/log/secure,red,'ALERT'
.SH BUGS
.PP
\- width must be larger than the longest file-header, otherwise segfaults.
.PP
Should you happen to find any bugs please fix them and send me a diff.
