Ruby question: Purpose of "ruby -run"?

+INSTALL_EXTRA_SWIG_RB=\
+ $(RUBY) -run -e mkdir -- -p
$(DESTDIR)$(SWIG_RB_SITE_LIB_DIR)/svn/ext; \
+ (cd $(SWIG_RB_DIR); \
+ find svn \
+ -name "*.rb" \
+ -exec $(RUBY) -run -e install -- \
+ $(SWIG_RB_DIR)/\{\} \
+ $(DESTDIR)$(SWIG_RB_SITE_LIB_DIR)/\{\} \;)
+

What is the advantage of "ruby -run" over invoking the command directly?

Max.
