&nbsp;<br>
The&nbsp;user&nbsp;can&nbsp;decide&nbsp;what&nbsp;program&nbsp;to&nbsp;run,&nbsp;and&nbsp;if&nbsp;he&nbsp;uses&nbsp;eg.&nbsp;'vim',&nbsp;the<br>
function&nbsp;app_vim()&nbsp;will&nbsp;be&nbsp;called.&nbsp;&nbsp;However,&nbsp;usually&nbsp;the&nbsp;user<br>
simply&nbsp;wants&nbsp;to&nbsp;"start"&nbsp;the&nbsp;file&nbsp;without&nbsp;specific&nbsp;instructions.<br>
In&nbsp;such&nbsp;a&nbsp;case,&nbsp;app_default()&nbsp;is&nbsp;called,&nbsp;where&nbsp;you&nbsp;should&nbsp;examine<br>
the&nbsp;context&nbsp;and&nbsp;decide&nbsp;which&nbsp;program&nbsp;to&nbsp;use.<br>

containing&nbsp;the&nbsp;whole&nbsp;command&nbsp;or&nbsp;a&nbsp;tuple&nbsp;containing&nbsp;a&nbsp;list&nbsp;of&nbsp;the<br>
