# If indexes don't index, run:	"texindex ess.??" to obtain the sorted indices.

### Targets below here are only for developers. --------------------


### Replace Version numbers (as in ../lisp/Makefile !):
## Use $(shell ..) only here, so only these are GNU make dependent :
README.SPLUS4WIN announc.texi inst_*.texi : ../VERSION
	perl -pi -e 's/$(ESSVER_NR_REGEXP)/$${1}-$(shell cat $^)/go' $@

readme.texi : ../VERSION
	perl -pi -e 's/($(ESS_REGEXP) \s*[Vv]ersion)\s+$(VER_NR_REGEXP)/$${1} $(shell cat $^)/go' $@

## ess.texi: use the perl for the above two combined:
ess.texi : ../VERSION
	perl -pi -e 's/$(ESSVER_NR_REGEXP)/$${1}-$(shell cat $^)/go;s/($(ESS_REGEXP) \s*[Vv]ersion\s+)$(VER_NR_REGEXP)/$${1}$(shell cat $^)/go' $@


##dist-doc: $(DOCDISTFILES)
##	@echo "**********************************************************"
##	@echo "** Making distribution of ESS-DOC for release $(shell cat $^)"
##	@echo "**********************************************************"
##	tar hcovf $(VERSIONDIR)-doc.tar $(DOCDISTFILES)
