This is the name of the strip(1) program, which removes symbol-table information from a program and creates a smaller binary. The default is the name strip. To strip a program with Build, install it with install-strip instead of install:

% ./Build install-strip 
Configuration: pfx=, os=SunOS, rel=4.1.3, rbase=4, rroot=4.1, arch=sun4, sfx=
Making in ../obj.SunOS.4.1.3.sun4/praliases
install -c -o bin -g bin -m 555 praliases /usr/etc
strip  /usr/etc/praliases                                        note

In rare circumstances, you might need to use a different program or a differently located version of strip to perform this function. You change strip with the confSTRIP build macro:

define(`confSTRIP', `/usr/new/44BSD/strip')

If you wish to always strip the binary, you can use the confLDOPTS macro (see confLDOPTS for a description of this end-run).
