I have found several funny lines in manuals for free software. Here seems as good a place as any to compile them. I suspect that some of these are just how the authors of Texinfo manuals stay sane.
CAUTION: This subsubsection has been reported to cause headaches. You might want to skip it upon first reading.
- info gawk, section 9.1.3.1
Beware that 'm4' may be dangerous for the health of compulsive programmers.
- info m4, section 1.1
In this case, I would suggest reading the whole of section 1.1 for the full experience. This is just the punchline.
false - do nothing, unsuccessfully
- man false(1)
Never use this function.
- man gets(3)
BUGS
It's too big and too slow.
- man bash(1)
More may be added in the future.
