Use an m4 build file in alternative directory

Build switch

The Build program uses m4 (1) to create a Makefile . The m4 directives useful for Build are listed in Section 2.4. This -f switch specifies the file to pass to m4 (1) to create a customized Makefile :

 %  ./Build -f ../../builds/oursite.m4  Configuration: os=SunOS, rel=4.1.4, rbase=4, rroot=4.1, arch=sun4, sfx= Using M4=/usr/5bin/m4 Creating obj.SunOS.4.1.4.sun4 using ../devtools/OS/SunOS Including ../../builds/oursite.m4   note  ... 

This -f switch allows you to maintain Build configurations separate from the source distribution. Whenever you use -f , a comment is automatically inserted into the resulting Makefile recording that fact. The command line, for example, will produce the following comment:

 #################################################################### ##### This file is automatically generated -- edit at your own risk ##### Built by [e-mail] ##### on Sat Jan 1 05:08:38 PDT 2000 using template OS/SunOS ##### including ../../builds/oursite.m4   note  ##### in /usr/local/src/sendmail-8.12.7/src #################################################################### 

Note that this build-configuration information is only preserved in the Makefile . No strings are compiled into sendmail , so it is not possible to reconstruct Build settings from the compiled binary.

If this switch is omitted, default files in the devtools/Site directory are used. See Section 2.5 for a full description of this process.

Note that the -Q and -f switches cannot be used together.
