when doing a :

r = IO.popen( cmd )

are the outputs of the cmd still separated in $stdout and stderr ?

how to retrieve them.

my basic usage is for an xslt transform (xslt 2.0) using saxon8.jar :

cmd = java -cp ../saxon-resources8-9/saxon8.jar net.sf.saxon.Transform
\"#{the_xml_file}\" \"#{the_xsl_file}\""
