+<avi-file> <chunk-path>
+
+.SH DESCRIPTION
+
+The utility is designed to assist in extracting chunk from RIFF files. The main
+(and only) reason why it was developed is to sort video files created by camera
+by date.
+
+.SH OPTIONS
+
+.TP
+\fB-1\fR, \fB--first\fR
+Stop after extracting the first matching chunk.
+.TP
+\fB-h\fR, \fB--help\fR, \fB--usage\fR
+Display short usage instructions and exit.
+.TP
+\fB-V\fR, \fB--version\fR
+Report version and exit.
+.TP
+\fB-L\fR, \fB--license\fR
+Show licensing terms.
+
+.SH EXAMPLE
+
+The command line invokation
+
+\fBiii-extract-riff-chunk DSC_0001.AVI '/RIFF.AVI /LIST.ncdt/nctg'\fR
+| dd bs=1 skip=82 count=19 2>/dev/null
+
+produces output
+
+YYYY:MM:DD HH:MM:SS
+
+at least for my Nikon D90 recorded AVI files.

 .SH NAME
 
 iiid \- An eye-fi card management daemon
 
 .SH SYNOPSYS
 
 \fBiiid\fR
 [\fB-h\fR] [\fB--help\fR] [\fB--usage\fR]
 [\fB-V\fR] [\fB--version\fR]
 [\fB-L\fR] [\fB--license\fR]
 [\fB-p\fR \fIport\fR] [\fB--port=\fR\fIport\fR]
 
 .SH DESCRIPTION
 
 iiid daemon is a minimalistic open source eye-fi management daemon
 implementation. It is listening for incoming connections and accepts files from
 eye-fi card, optionally invoking scripts to sort out files or send out
 notifications.
 
 .SH OPTIONS
 
 .TP
 \fB-p\fR \fIport\fR, \fB--port=\fR\fIport\fR
 Set the port to listen to. You're not likely to ever need to change this,
 perhaps for debugging purpose or if you want to proxy connections.
 .TP
 \fB-h\fR, \fB--help\fR, \fB--usage\fR
 Display short usage instructions and exit.
 .TP
 \fB-V\fR, \fB--version\fR
 Report version and exit.
 .TP
 \fB-L\fR, \fB--license\fR
 Show licensing terms.
 
 .SH EXIT STATUS
 
 The daemon isn't supposed to exit at this point, but, like most executables, it returns zero in case of success, non-zero otherwise.
 
 .SH FILES
 
 .TP
 @sysconfdir@/iii/\fBXXXXXXXXXXXX.conf/fR
 Upon successfull connection, the daemon reads the configuration from this file,
 where XXXXXXXXXXXX is the macaddress of your eyefi card. You can lookup the mac
 address of your card in your Mac/Windows Settings.xml file. Be sure to remove
 dashes from it.
 
 .SH CONFIGURATION OPTIONS
 
 .TP
 \fBtargetdir\fR = "\fI/var/lib/iii/%s/\fR"
 Sets the target directory for uploaded files. If the \fI%s\fR placeholder is
 present in the string, it is replaced with card mac address.
 .TP
 \fBuploadkey\fR = "\fIxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\fR"
 The upload key as seen in Mac/Windows Settings.xml file.
 .TP
 \fBon-start-session\fR = "\fIlogger iii-StartSession ${EYEFI_MACADDRESS} ${EYEFI_TRANSFER_MODE} ${EYEFI_TRANSFERMODETIMESTAMP}\fR"
 The command to execute on \fBStartSession\fR request. The command receives some
 information via environment variables.
 .TP
 \fBon-upload-photo\fR = "\fIlogger iii-UploadPhoto ${EYEFI_MACADDRESS} ${EYEFI_UPLOADED}\fR"
 The command to execute after successfull photo upload. The information about
 the card mac address and uploaded file name is passed via environment
 variables.
 .TP
 \fBon-mark-last-photo-in-roll\fR = "\fIlogger iii-MarkLastPhotoInRoll ${EYEFI_MACADDRESS} ${EYEFI_MERGEDELTA}\fR"
 The command to execute on \fBMarkLastPhotoInRoll\fR request. The information
 about request is passed via environment variables.
 .TP
 \fBumask\fR = \fI002\fR
 The file mode creation mask.
