## Program and Process

We will talk a lot about the running "**process**", so it's useful to have clarity about what it means, and what's the difference with the word "**program**".

### What is a Program

The word **program** is commonly used to describe many things:

* The **code** that you write, the **Python files**.

func Lower(t language.Tag, opts ...Option) Caser {
	return Caser{makeLower(t, getOpts(opts...))}
}

// Title returns a Caser for language-specific title casing. It uses an
// approximation of the default Unicode Word Break algorithm.
func Title(t language.Tag, opts ...Option) Caser {
	return Caser{makeTitle(t, getOpts(opts...))}
}

// Fold returns a Caser that implements Unicode case folding. The returned Caser

	OpBeginText                    // matches empty string at beginning of text
	OpEndText                      // matches empty string at end of text
	OpWordBoundary                 // matches word boundary `\b`
	OpNoWordBoundary               // matches word non-boundary `\B`
	OpCapture                      // capturing subexpression with index Cap, optional name Name
	OpStar                         // matches Sub[0] zero or more times
