# ====One page per file with page range
# Convert.new("/dir/myfile.pdf").to :eps, :multipage => true, :filename => "/tmp/test.eps", :range => 1..5

# ====Getting files after convertion
# files=Convert.new("/dir/myfile.pdf").to :eps, :multipage => true, :filename => "/tmp/test.eps", :range => 1..5
# files.class # => Array because parameter multipage is true
#
# file=Convert.new("/dir/myfile.pdf").to :eps, :filename => "/tmp/test.eps"
# file.class # => File
