I usually need to browse through lots of RFCs, both for work and leisure. Reading them in the browser or even a PDF reader is quite not right for me and long ago I found the ultimate tool for RFC reading on my computer: qRFCView.
However, one day I wanted to read RFC6026 and suddenly I realized that for some reason qRFCView wouldn’t let me choose a RFC number greater than 5000.
A quick search led me to know that the number is hardcoded 🙁 It’s listed as an important bug in Debian since january 2009.
The fix is really easy, just get the Debian source for qrfcview, modify src/main.cpp, raise the number to 9999 or whatever you think it’s best and debuild again.
