Merge Pdfs

When we need to merge different pdfs or ps files into one, 'gs' interpreter is the best. Merging files is easy just list the files to be concatenated on the command line and the merged file shall be created at the locations provided.

Example:
gs - dNOPAUSE -sDEVICE=pdfwriter -sOUTPUTFILE=Merged.pdf -dBATCH 1.pdf 2.pdf .......(in order we want them to be merged).....
