+If your package installs Perl scripts, also import the
+@code{relocatable-perl} module. Then, near the beginning of each
+Perl script that your package installs, add the following:
+
+@example
+@@relocatable_pl@@
+if ("@@RELOCATABLE@@" eq "yes") @{
+ my $exec_prefix = "@@exec_prefix@@";
+ my $orig_installdir = "@@bindir@@"; # see Makefile.am's *_SCRIPTS variables
+ my ($orig_installprefix, $curr_installprefix) = find_prefixes($orig_installdir, find_curr_installdir());
+ sub relocate @{ # the subroutine is defined whether or not the enclosing block is executed
+ my ($dir) = @@_;
+ if ("@@RELOCATABLE@@" eq "yes") @{
+ $dir =~ s%^$orig_installprefix/%$curr_installprefix/%;
+ $dir =~ s,/$,,;
+ @}
+ return $dir;
+ @}
+@}
+
+# Get some relocated directory names.
+$sysconfdir = relocate("@@sysconfdir@@");
+$some_datadir = relocate(@@datadir@@/something");
+@end example
+
+You must adapt the definition of @code{$orig_installdir}, depending on
+where the script gets installed. Also, at the end, instead of
+@code{sysconfdir} and @code{some_datadir}, transform those variables
+that you need.

In your @file{Makefile.am}, for every program @command{foo} that gets
installed in, say, @file{$(bindir)}, you add:
