.B PONYSAY_BOTTOM
Under TTY (Linux VT), if the output is larger the the screen's height, only the beginning is
printed, leaving 2 blank lines. If you want the buttom to be printed rather the the beginning
printed, leaving two blank lines. If you want the buttom to be printed rather the the beginning
you can export \fBPONYSAY_BOTTOM\fP with the value \fIyes\fP, \fIy\fP or \fI1\fP.
.B PONYSAY_SHELL_LINES
Under TTY (Linux VT), if the output is larger the the screen's height, two lines are left blank.
If you want moer, or less, blank lines you can export \fBPONYSAY_SHELL_LINES\fP with the value
of how many blank lines you want. Naturally this takes effect if the output is not actually larger
than the screen.
.B PONYSAY_FULL_WIDTH
You can export \fBPONYSAY_FULL_WIDTH\fP with the value \fIno\fP, \fIn\fP or \fI0\fP, if you
do not want the output to be truncated on the width to fit the terminal.
