I love CiteULike. It makes keeping a bibtex library easy and keeps all my papers in one place. However, it can be a pain when I add new entries and have to go through the procedure for downloading the new version in my browser, so I made this to grab it for me! I actually pipe it directly into a couple of SED one liners to tidy it up a bit too. Extremely useful, especially if you make a custom BibTeX script that does this first. That way you can sort a fresh BibTeX file for each new paper with no faf.

To use just replace with your CiteULike user name. It doesn't download entries that you've hidden but I don't use that feature anyway.

It's sometimes useful to strip the embedded fonts from a pdf, for importing into something like Inkscape. Be warned, this will increase the size of a pdf substantially.

I tried this with only gs writing with -sDEVICE=pdfwrite but it doesn't seem to work, so I just pipe postscript output to ps2pdf for the same effect.
