The YML ¬http://en.wikipedia.org/wiki/Compiler compiler¬ is a small |
|
15 |
¬http://www.python.org Python script¬. It provides the |
|
16 |
¬http://en.wikipedia.org/wiki/Command-line_interface command line¬ front end «yml2c». |
|
17 |
As default, it compiles your ¬http://en.wikipedia.org/wiki/Scripting_language script¬ |
|
18 |
and outputs to ¬http://en.wikipedia.org/wiki/Stdout#Standard_output_.28stdout.29 stdout¬, |
|
19 |
that usually is the ¬http://en.wikipedia.org/wiki/Computer_terminal terminal¬. |
|
20 |
Your ¬http://en.wikipedia.org/wiki/Shell_(computing) shell¬ provides options to redirect |
|
21 |
the output into a ¬http://en.wikipedia.org/wiki/Pipeline_(Unix) pipe¬ or |
