all methods are actually static, the class is just needed for namespace emulation to conform with PEAR naming conventions
void dosify( string $text, string 1)
string indent( int $level, string $text)
Overridden in child classes as:
string linetrim( string $text)
string tabify( string $text, [int $tabsize = 4])
PHP C coding conventions require tab indention with a tabsize of 4
string untabify( string $text, [int $tabsize = 4])
PEAR PHP coding conventions require blank indention with a tabsize of 4
