devel/ht 2.1.0nb3 NetBSD

ht is a file viewer, editor and analyzer for text, binary, and (especially) executable files. It recognizes the most common executable formats, like COFF, ELF, LE, MZ, NE, PE32, PE64 and Java .class files, and can disassemble them.

It can also find branch sources and destinations recursively, find procedure entries, creates labels based on this information, create xref information, interactively analyse unexplored code, create/rename/delete labels and create/edit comments.
