    Python strings are immutable objects.  This has the advantage, that
    strings may be used as dictionary keys.  If this property isn't needed
    and you insist on changing string values in place instead, you may cheat
    and use MutableString.

    But the purpose of this class is an educational one: to prevent
    people from inventing their own mutable string class derived
    from UserString and than forget thereby to remove (override) the
    __hash__ method inherited from UserString.  This would lead to
    errors that would be very hard to track down.

    A faster and better solution is to rewrite your program using lists."""

def getdirs(self, libname)

Implements the dylib search as specified in Apple documentation:

Before commencing the standard search, the method first checks the bundle's Frameworks directory if the application is running within a bundle (OS X .app).

class MutableString (string='')

mutable string objects

Python strings are immutable objects. This has the advantage, that strings may be used as dictionary keys. If this property isn't needed and you insist on changing string values in place instead, you may cheat and use MutableString.

But the purpose of this class is an educational one: to prevent people from inventing their own mutable string class derived from UserString and than forget thereby to remove (override) the hash method inherited from UserString. This would lead to errors that would be very hard to track down.

A faster and better solution is to rewrite your program using lists.
