On producing pdf files

The manuscript of Open Computing is written in AmS-TeX. To produce the pdf file from the dvi file open.dvi, the following commands were used in a Red Hat Linux 7.2 environment (the $ sign indicates the prompt):

$ dvips -Ppdf -o open.ps open.dvi
$ ps2pdf open.ps

The important point here is the -Ppdf option of the first command, which makes sure that Type 1 PostScript fonts are used in the resulting PostScript file open.ps. Normally, dvips produces Type 3 PostScript fonts, but these look very bad with the current acroread pdf reader; they look OK with ghostview. The second command produces the pdf file open.pdf.
