There is no "make install", just copy the +miragextract binary to /usr/local/bin and the man page (miragextract.1) +to /usr/local/share/man/man1, or whatever paths make sense on your OS. +There's also a miragextract.html, if you prefer your documentation +that way. --t takes a track number, and extracts only that one track. Default -behaviour is to extract all tracks. +Supported formats +----------------- +According to the README from libmirage-3.2.4: --b sets the basename for the output files.
