I have developed little application saveURL it is not meant to run directly but this binary is executed by read_redif_mod. What this applicatio do? I modified read_redif to read_redif_mod which not just read rdf file for handle or text related to it but also creates 3 temporary log file in ~/log directory which is removed after the operation is completed. It also exec saveURL binary which in turn reads ~/log/* files for rdf file path, handle, and handle text (string). function performed by saveURL:: It gets the time stamp of rdf file reverse it and create dir like ~/720/820 It than percent encode the handle name and creates the file with percent encoded handle name (as stated in fort lee doc) with handle text in it. Example is given below http://archec.repec.org/720/905/9611_RePEc%253Aqut
