Each time PV-WAVE starts, it looks for a file named motd in $WAVE_DIR/bin. If this file exists, its contents are printed out just before the first PV‑WAVE prompt is displayed. This file can be used to inform users of changes to PV-WAVE, the date of the most recent update and other information of interest.

To create a message of the day file, use a text editor to create a file named motd in the directory $RW_DIR/wave/bin. The message is displayed exactly as it appears in the message file.
