## Generating include scripts for all Nuget packages

It is possible to generate include scripts for all registered Nuget packages defined in paket.dependencies.

[lang=batchfile]
$ paket generate-include-scripts framework net45

This will create .csx and .fsx scripts under `paket-files/include-scripts/net45/`, those files can now be
used in your scripts without having to bother with the list and order of all dependencies for given package.

Note: this command only works after packages have been restored, please call `paket restore` before using `paket generate-include-scripts` or `paket install` if you just changed your `paket.dependencies` file.

can we make it call restore (in a future PR)?

You mean having the command itself call restore to remove the need from the user?

If you think that's the sensible choice, yes I can make a PR for this.

Similarly, do you have an idea about how it should interact with "garbage collection" story?

I think create script should do a restore.
I think gc should be extended to clean unused load scripts

## Sample

Consider the following paket.dependencies file:

[lang=paket]
source https://nuget.org/api/v2

nuget FsLab

Now we run `paket install` to install the packages.

Then we run `paket generate-include-scripts framework net45` to generate include scripts.

in a .fsx script file you can now use

[lang=fsharp]

#load @"paket-files/include-scripts/net45/include.fslab.fsx"

// now ready to use FsLab and any of it's dependencies

you'll see messages when you execute the `#load` line in FSI:
