+# 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.
