Editing configuration files

[Giuseppe Fuggiano]

Hi there.

For some years I used Vim, but currently I'm missing some important 
features to use for coding and debugging.

Today, I'm passing to Emacs as a editor of choice for every editing 
purposes, but I'm missing the Vim's automatic highlighting when opening 
configuration files.

I tried M-x conf-mode but it's imperfect. For example, if I edit 
/etc/crontab in Vim, it highlights correctly every field and variable.

What can I do to make Emacs try to highlight every configuration file 
like Vim?

Thanks!
