# oper-:arch-:syst-:chip-:kern-
# oper = operating system type; e.g., sunos-4.1.4
# arch = machine language; e.g., sparc
# syst = which binaries can run; e.g., sun4
# chip = chip model; e.g., micro-2-80
# kern = kernel version; e.g., sun4m
# dependence: arch --- chip
# \ \
# oper --- syst --- kern
# so, for example, syst is interpreted in light of oper, but chip is not.
# anyway, no slashes, no extra colons, no uppercase letters.
# the point of the extra -'s is to ease parsing: can add hierarchies later.
# e.g., *:i386-*:*:pentium-*:* would handle pentium-100 as well as pentium,
# and i386-486 (486s do have more instructions, you know) as well as i386.
# the idea here is to include ALL useful available information.
