suggestion: my excludes, necessary / useful

To successfully complete a `timemachine` backup of my Ubuntu home directory, I had to **exclude** certain special files which can't be backupped. I maintain an `--exclude-from` file, to get my backup done:

necessary excludes to finish a backup of my Ubuntu desktop's `home` directory without error
[$USER]/.dbus
*.sock

other excludes, to make it nicer
**/Trash/
/.Trash**/
[$USER]/.cache/
**/*cache/
**/*Cache/
**/*CACHE/
lost+found

other excludes, especially because I have `netatalk` running:
[$USER]/.AppleDB/
[$USER]/.AppleDesktop/
**/.AppleDouble/
[$USER]/Network\ Trash\ Folder/
/Temporary\ Items/
.DS_Store

_remark_:
Not sure if a pattern like `[$USER]` will work. In my case I have simply written the literal _name_ of my SOURCE directory.
