| In normal operation mode, standard input is copied to standard output, |
| with references to environment variables of the form $VARIABLE or ${VARIABLE} |
| being replaced with the corresponding values. If a SHELL-FORMAT is given, |
| only those environment variables that are referenced in SHELL-FORMAT are |
| substituted; otherwise all environment variables references occurring in |
| standard input are substituted. |
| .PP |
| When \fB\-\-variables\fR is used, standard input is ignored, and the output consists |
| of the environment variables that are referenced in SHELL-FORMAT, one per line. |
