+.SH "NAME"
+sigrok\-fwextract\-sysclk\-lwla1034 \- Extract SysClk LWLA1034 firmware
+.SH "SYNOPSIS"
+.B sigrok\-fwextract\-sysclk\-lwla1034 SETUP-EXE
+.SH "DESCRIPTION"
+This tool extracts FPGA bitstreams from the vendor software for the SysClk
+LWLA1034 USB logic analyzer. Insert the CD-ROM that ships with the device,
+and locate the Windows installer executable "lwla1034_EN_setup.exe".
+.PP
+In order to extract the bitstreams, run the following command:
+.PP
+.B "  $ sigrok-fwextract-sysclk-lwla1034 lwla1034_EN_setup.exe"
+.PP
+Copy the resulting four bitstream files over to the location where libsigrok
+expects to find its firmware files. By default this is
+.BR /usr/local/share/sigrok-firmware .
+.SH OPTIONS
+None.
+.SH "EXIT STATUS"
+Exits with 0 on success, 1 on most failures.
+.SH "SEE ALSO"
