if errorlevel 1 goto :eof

In ruby:
#
validate_all = true if ARGV.include?("-va")

def issue(message, command)
  puts message
  system(*command) or exit 1
end

issue "validating source XML:", %w"domcount svg-links.xml"
issue "source to xhtml:", %w"java com.icl.saxon.StyleSheet -o links.xhtml svg-links.xml links2xhtml.xslt"
#
if validate_all
  issue "validating xhtml:", %w"domcount links.xhtml"
end
#
issue "source to dot:", %w"java com.icl.saxon.StyleSheet -o links.dot svg-links.xml links2dot.xslt"
#
issue "dot to svg:", %w"dot -Tsvg -o links.svg links.dot"
#
if validate_all
  issue "validating SVG:", %w"domcount links.svg"
end
#


But I'll choose Makefile in such case:
# make [va]
VALIDATE = domcount
DOT2SVG = dot -Tsvg
MAKELINKS = java com.icl.saxon.StyleSheet

SOURCE = svg-links.xml
XHTML = links.xhtml
DOT = links.dot
SVG = links.svg

.SUFFIXES: .dot .svg

.dot.svg:
	$(DOT2SVG) -o $@ $<

all: $(XHTML) $(SVG)

va: valid-$(XHTML) valid-$(SVG)

$(XHTML): $(SOURCE) valid-$(SOURCE)
	$(MAKELINKS) -o $@ $(SOURCE) links2xhtml.xslt

$(DOT): $(SOURCE) valid-$(SOURCE)
	$(MAKELINKS) -o $@ $(SOURCE) links2dot.xslt

valid-$(SOURCE): $(SOURCE)
	$(VALIDATE) $(SOURCE)

valid-$(XHTML): $(XHTML)
	$(VALIDATE) $(XHTML)

valid-$(SVG): $(SVG)
	$(VALIDATE) $(SVG)
