Idea for Nautilus and GMC.

[Miguel de Icaza]

Currently when people download executables from the network, say for
installing software, they can not execute them because the execute bit
is not set.

So typical installation instructions for a Unix application look like
this:

	1. Click on this link to download.
	2. Run a shell
	3. type chmod +x file
	4. Run

Ideally, we want to avoid this problem in GNOME, and we just want
executables to just work.  As they do in Windows.  

So I would like to suggest that we set this bit manually if the user
double clicks on a file that happens to have an a.out or ELF
signature.  Maybe we could popup a warning or something, but the
result should be that files downloaded in this way would just work.

Comments?

Miguel.
