helpGet help on Xselect commands
Obtain help on the XSELECT commands, their syntax, and examples. Help uses the IHF interactive help facility. The optional topic list can be used to go directly to a particular topic and sub-topic. Once in help, typing ?? will summarise extra features and special characters that can be used within the IHF system. To exit back to XSELECT, use an EOF, a /*, or type CR until you leave the help facility. Syntax:
xsel > help <topic list> Examples:
xsel > help help gives the text you are reading.
xsel > help "commands extract" gives the text for the extract command.
