ANSIEscapeHelper is an Objective-C class for dealing with ANSI escape sequences. Its main purpose is to translate between NSStrings that contain ANSI escape sequences and similarly formatted NSAttributedStrings.

Here's a quick and simple example of how you'd most likely want to use this class:

AMR_ANSIEscapeHelper *ansiEscapeHelper =
    [[[AMR_ANSIEscapeHelper alloc] init] autorelease];

// display an ANSI-escaped string in a text view:
NSString *ansiEscapedStr =
    @"Let's pretend this string contains ANSI escape sequences";
NSAttributedString *attrStr = [ansiEscapeHelper
[[nsTextViewInstance textStorage] setAttributedString:attrStr];

// get an ANSI-escaped string from a text view:
NSAttributedString *attrStr = [nsTextViewInstance textStorage];
NSString *ansiEscapedStr = [ansiEscapeHelper
