bbe is a sed-like editor for binary files. Instead
of reading input in lines as sed, bbe reads
arbitrary blocks from an input stream and performs
byte-related transformations on found blocks.
Blocks can be defined using start/stop strings,
stream offset and block length, or a combination.
Basic editing commands include delete, replace,
search/replace, binary operations (and, or, etc.),
append, and bcd/ASCII conversion. For examining
the input stream, it contains some grep-like
features like printing the input file name, stream
offset, and block number of found blocks. Block
contents can also be printed in different formats
like hex, octal, ASCII, and binary.
