The format is as follows (lines beginning witha '#' are ignored as comments):<p> <pre>[Desktop Entry]# the line above is mandatory at the beginning of the file# Exec specifies the name of the executable that should be in /opt/Qtopia/binExec=executablename# This should always be Application for links to applications.Type=Application# Specifies the icon to be found in /opt/Qtopia/pics.
