1 | # Top-level makefile for Exim; handles creating a build directory with |
2 | # appropriate links, and then creating and running the main makefile in that | |

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

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