• Rich API - chances are that whatever you want to do there’s a simple and elegant way of doing it.

• Bit level slicing, joining, searching, replacing and more.

• Create bitstrings from hex, octal, binary, files, formatted strings, bytes, integers and floats of different endiannesses.

• Powerful binary packing and unpacking functions.

• Read from and interpret bitstrings as streams of binary data.
