/usr/local/bin vs /opt

[jerry1]

Can someone give me insight here.

/opt - opt has always been for installing
middleware/third party packages
basically.
/usr/local/bin - for basically home grown scripts, binaries.

I am starting to find that porters are now
dumping gcc, perl tools all in /usr/local/bin.

This seems to be a messy way of installing
software especially if one of the files from
these distributions happens to have the same
name and overwrites my custom files.

One of these sites is the HP Porting Center.

What do you think?
