4# appropriate links, and then creating and running the main makefile in that
5# directory.

10# IRIX make uses the shell that is in the SHELL variable, which often defaults
11# to csh, so put this in to make it use the Bourne shell. In systems where
12# /bin/sh is not a Bourne-compatible shell, this line will have to be edited,
13# or "make" must be called with a different SHELL= setting.

17# If a build name has not been specified by running this make file via a
18# command of the form "make build=xxxx", then determine the name of the
19# operating system and the machine architecture and use that. This does not
20# provide an override for the OS type and architecture type; they still have
21# to be used for the OS-specific files. To override them, you can set the
22# shell variables OSTYPE and ARCHTYPE when running make.
