An easy way to Spilt or Merge PDF Files in Linux

I work as  the IT guy of a school that runs free software on all our computers. So far majority of our computing needs has been  met by free software. ( all of them if we exclude matlab and some freedom hating multimedia  codecs.) One area that has been quite shaky is a good tool that can be used for merging different pdf files into one. There is a tool called pdftk but its command-line and while i don’t have a problem using it,  its hardly the tool i want to recommend for our  staffs and students,  so when this morning i saw a dent on identi.ca about a tool called PDF-Shuffler which among other things provide an easy way to merge PDF files i decided to to Investigate.

PDF-Shuffler is a small python-gtk application, which helps the user to merge or split PDF documents. You can also rotate, crop and rearrange their pages using an interactive and intuitive graphical interface.

unfortunately sage is not available in the Ubuntu repositories and in-fact any repositories as a .deb package. ( at the time of writing this). did you say compiling? dont even go there i tried building it. and failed woefully. fortunately i found a nice and easy to install it on Ubuntu. there is a binary package already compiled for Ubuntu. which makes installation on Ubuntu quite easy and straight forward.
