2010-04-10 Fiddled around with refer. The problem was two adjacent refs with nroff's referencing style (... [ref] ...) in troff. After digging into refer's sources I discovered that I can solve it by sorting the refs. Futher more, I created a table of contents and modified the NH macro in ms to have different font sizes. Learning software requires using it. http://marmaro.de/lue/ markus schnalke
