'rom_tool' is a command line tool designed to check/manipulate CTR Cartridge Image (CCI) files, usually referred to in the 3DS Scene as "3DS ROM dumps".
Its major use is to reduce the size of CCI files (trimming) by removing dummy bytes(and being able to restore them again). Trimmed CCI files are compatible with the Gateway 3DS flash cart, and associated clones.
