8# AM_PROG_INSTALL_STRIP
9# ---------------------
10# One issue with vendor 'install' (even GNU) is that you can't
11# specify the program used to strip binaries.  This is especially
12# annoying in cross-compiling environments, where the build's strip
13# is unlikely to handle the host's binaries.
14# Fortunately install-sh will honor a STRIPPROG variable, so we
15# always use install-sh in "make install-strip", and initialize
16# STRIPPROG with the value of the STRIP variable (set by the user).

19# Installed binaries are usually stripped using 'strip' when the user
20# run "make install-strip".  However 'strip' might not be the right
21# tool to use in cross-compilation environments, therefore Automake
22# will honor the 'STRIP' environment variable to overrule this program.
23dnl Don't test for $cross_compiling = yes, because it might be 'maybe'.
