Postscript?! Until starting university, I had not
encountered files in Postscript format before (I had heard of it, but not encountered). It
seems to be a very common thing on UNIX platforms.
To put things in perspective. Postscript is not such
on odd format. Pdf is basicially a souped-up form
of postscript. Furthermore a lot of printer use postscript.
A lot of programs can generate postscript, even on Win32 (for instance
Word, IE). There is also a free postscript
viewer (Ghostscript), this also runs on Win32.
Also, while pdf is nice (seach and hyperlinks are useful)
it is also a proprietary format, the readers are free,
but you have to pay money for the distiller.
