When I just read your quote, this joke came to mind:
What's the difference between a public library and a software library ?
At the public library, everyone wants to check things out, but no-one
ever wants to return anything. In a source code library, everyone wants
to put something in the library, but programmers rarely want to take
anything in it out, and use it.
Maybe it doesn't seem as funny as the first time I heard it, but I think
it's still true. Maybe a similar thought is behind the 'source motel'
quote.

There's a funny quote from Ken Thompson that circulates from time-to-time:
"SCCS, the source motel! Programs check in and never check out!"
But nobody seems to know what it means exactly. As part of my
research, I asked Ken what the quote meant, sunce I wanted to include
it. He explained that it refers to SCCS storing binary data in its
repository file, preventing UNIX text tools from operating on the file.
Of course, this is only one of SCCS's many weaknesses. If you have
anything funny about any of the others, post it here. I already have
all the boring usual stuff (e.g., long-term locks, file-oriented, no
merging).
