# least is a selective pager.  If the file paged fits in the terminal it 
# will be sent to stdout (as if you used cat), if the lines paged do not
# fit on one screen it will use your $PAGER.
#
# Someone commented that this is what 'less -FX' does -- which it does.  
# least is only useful if your PAGER != less ... like in my case.
#
# example:
#    cat file | least
#    least file1 file2
#
# you can put this in your .bashrc
#
