{title:Description}

{pstd}
A {bf:quine} is a computer program that prints itself out when run. A quine is not allowed to load any data and must contain any data that it uses. Hence, entering
 the command {bf:quine} at the Stata command prompt results in the {bf:quine} command reproducing itself. 

{title:Comments}

{pstd}
The {browse "http://en.wikipedia.org/wiki/Quine_(computing)":Wikipedia entry for quines} has some historical information on quines, including the origins
of the term "quine." Creating a quine takes a little finesse, but the basic idea can be summed up by the psuedo-code: 

{pstd}
{it: Print whatever follows this statement in quotes twice, the second time in quotes: "Print whatever follows this statement in quotes twice, the second time in quotes:"}
