Re: The 'populate' script

Yan, All,

That is exactly what I expected, however, the 'find' result didn't agree:

$ sudo find / -name "*populate*" -print
/usr/local/src/crosstool-ng-1.8.2/scripts/populate.in
/usr/local/src/gccCross/targets/src/gcc-4.4.3/libstdc++-v3/testsuite/util/io/text_populate.hpp
/usr/local/src/gcc-4.5.1/libstdc++-v3/testsuite/util/io/text_populate.hpp
/usr/local/lib/ct-ng-1.8.2/scripts/populate.in
/usr/bin/svn-populate-node-origins-index
/usr/src/linux-headers-2.6.32-21-generic/include/config/arch/populates

As you can see no such script found anywhere, would it be due to my
recent 'ct-ng build' break out in the middle of 'Installing binutils
for target' as reported earlier?  Any idea how to resolve this issue:

Loud and C L E A R!!!  :)  Explanation like this should add to overview.txt
