TDS says system/platform specific docs can be elsewhere, e.g.,
texmf/vms/help (or, more likely, texmf/windujour/help for .chm files).
I suppose texdoc could always be configured to add such directories
if anyone discovers the need and actually has sed, etc.

Think about people running tl in a linux VM or native linux on a P3
On my office P3 it took 45 s. for the first search, 11 for the 2nd
using the original
TL2007 texdoc. I tend to avoid texdoc in favor of locate.
"texdoc -S lm-info" is much faster than the old version, but "texdoc -S lm" is
slower. On the SGI at work (after editing "/bin/sh" --> /bin/ksh" and
"egrep -q"
--> "egrep -s") :
$ time texdoc -s lm
[...]
real 0m4.318s
user 0m0.095s
sys 0m1.021s
$ time texdoc -S lm
Directories that match lm:
/nfs/orion/disk2/TeX/texlive/2007/texmf-dist/doc/fonts/lm
/nfs/orion/disk2/TeX/texlive/2007/texmf-dist/doc/latex/elmath
/nfs/orion/disk2/TeX/texlive/2007/texmf-dist/doc/latex/epiolmec
Files that match lm
[...]
real 0m7.269s
user 0m4.571s
sys 0m1.351s
The difference is even greater for linux on P-III.
On a faster machine I tend to use locate or the full-text
index/search tools (beagle), so texdoc gets ignored.
