The intent is not to compete with python, perl, or shell languages, but rather to provide portable filesystem operations. Filesystem is implemented as a separately compiled library, so before using it you must install it in a location that can be found by your linker. Iostreams gives you access to more streams to read and write data from and to many different sources and sinks. The library name now includes the version suffix of the python version used to compile it. Although the standard library lacks some important features, you could always use boost with its thousands of sublibraries and do the work. In addition, many freestanding functions are available to handle tasks like creating directories or checking whether a file exists.
