I have added a which package to the tcllib v1.4 library
we are shipping with our Quartus II software developed
here at Altera. I thought I'd submit the package back
to the tcllib team for possible consideration as a
standard tcllib package. This is a pure-Tcl which
implementation that has the same interface on
Windows/Unix (eases cross-platform scripting a bit).
There's not much too it. It doesn't support MacOS (we
don't ship for MacOS so I have no way to test it) but
it shouldn't be hard to extend to the Mac platform.

Wrapper as fileutil::which is an idea. Renaming and
recategorizing the entry.

I agree that the name 'auto_execok' is ... non-intuitive /
non-explanatory. Historically grown, unfortunately. It came
out of the 'auto'loader and is a helper command for it.

Sure. Probably fine to close this. Unless you want to
consider wrapping auto_execok in a fileutil::which command.
I only never noticed auto_execok because, well, that command
name completely sucks. Without clicking through the
documentation on the tcl wiki page I would never have
guessed what it did from the command name.

Don't feel to bad. Nobody knows all, not even I, and that is
why things go through the review. Note that while
auto_execok is meant to do the same things it is a bit
different internally and the API, for more x-platform ability.

Should I  close this then ?

Oh, and don't let this stop you from proposing other modules
and code of yours for tcllib.

uhh...umm...well...i guess if i had read the docs for
auto_execok...i...uhh...well, probably wouldn't have written
this because they are the exact same thing. opps. don't i
feel silly now.

I agree that [auto_execok] likely does a
better job (especially when it comes to
platform differences), but if one just has a liking
for Unix-style shell commands, there's
a history of placing them in the
fileutils package, rather than having only
one command per package.

See for example, [fileutil::cat], [fileutil::find],
[fileutil::grep], etc.

After looking at the docs I have a question: The tcl core
has the builtin command 'auto_execok' which also does
searching for executables. How does your command compare to it ?
