List only apps that exist on current host

[haakonstorm]

Suggestion 1: "# mackup listlocal"

# mackup listlocal

To list only apps currently available on current host. Something along these lines:

Usage:
 mackup list
 mackup listlocal
 mackup [options] backup
 mackup [options] restore
 mackup [options] uninstall
 mackup (-h | --help)
 mackup --version

Options:
 -h --help     Show this screen.
 -f --force    Force every question asked to be answered with "Yes".
 -n --dry-run  Show steps without executing.
 -v --verbose  Show additional details.
 --version     Show version.

Modes of action:
1. list: display a list of all supported applications.
2. listlocal: display a list of all supported applications found on this local host**
(...)

The idea is that:
# mackup listlocal >> .mackup.cfg
can prepopulate the config file so it is easier to sort apps into:

[applications_to_sync]
irssi
ventrilo
xemacs

[applications_to_ignore]
xcode
rstudio

Because today, when I ran the utility for the first time with --dry-run, I got a list like this:
# mackup --dry-run backup

Backing up .MacOSX ...
Backing up Library/KeyBindings/DefaultKeyBinding.dict ...
Backing up Library/ColorSync/Profiles ...
Backing up .hgignore_global ...
Backing up Library/Application Support/Many Tricks ...
Backing up .npmrc ...
Backing up Library/Preferences/com.kapeli.dashdoc.plist ...
Backing up Library/KeyBindings/DefaultKeyBinding.dict ...
Backing up Library/Services ...
Backing up Library/Workflows ...
Backing up .config/omf ...
Backing up .subversion ...

I am not sure which apps all items in this list belong to. If instead we could do something like:

# mackup listlocal

xcode
sublime-text-3
alfred3
rstudio

(notice the dashes ("-") are removed from this view, to be compatible with .mackup.cfg)
This way your could immediately edit the cfg to select which Apps I want to exclude.

Suggestion 2: "# mackup setup"

Additionally, another way perhaps even better would be something like:

10core.local: # mackup setup

Searching for locally installed apps supported by the sync engines ...
Searching for available sync backends ...
Defaulting to all apps INCLUDED for sync ...
Building ~/.mackup.cfg for this particular host 10core.local ...
Done

Resulting in a .mackup.cfg created and prepopulated with:

• Preconfigured, commented-out configuration suggestion for sync backends found (iCloud/git/Dropbox/~/..)
• Preconfigured includes/excludes, defaulting to either all apps included or all apps excluded, or user selectable?
• Perhaps for each app, lines listing the files queued for sync so they can be user included/excluded on a per-file-per-app basis?

Just my 0.02 satoshis,
thanks for a great utility!
And for Pouet!

I really like this proposal. Otherwise mackup list is not very useful, having 400+ programs listed, most of which each individual user doesn't even recognize.
