Binary Dependency Resolution This header contains the functions needed to determine the dependencies needed for binary files. It does this both against traditional ELF binaries, leveraging LDD in libraries.hpp, but also supports tokenizing and parsing shell scripts to extract shebangs and commands used for dynamic dependency resolution. This support is far more nuanced than in Python-SB, as we incorporate variables and using the shell interpreter itself to uncover libraries and binaries inaccessible to the old tokenizer. More...
