-# The ABI to be used, if supported by the Operating System and/or compiler.
-# Currently only used under IRIX and explicitly set during bootstrapping
+# The Application Binary Interface (ABI) to be used, if supported by the
+# Operating System and/or compiler.
+#
 # Only change this if you really know what you're doing -- libraries of
 # one ABI can not be linked with libraries of another!
-# Possible: 64 (64 bit ABI), 32 (SGI's N32 ABI), undefined (SGI's old o32 ABI)
-# Default: determined during bootstrapping

+# Currently only usable on IRIX or Solaris. On IRIX, it is set
+# automatically by the bootstrap script, on Solaris, it is not.
+#
+# If you change it, be sure that _all_ the installed libraries and
+# programs have the same API and use consistent compiler options. It is
+# recommended that this variable be only changed directly after
+# bootstrapping pkgsrc.
+#
+# Possible values:
+#	* 64 (64 bit ABI; both IRIX or Solaris)
+#	* 32 (SGI's N32 ABI; only IRIX)
+#	* undefined (SGI's old o32 ABI; only IRIX)
