I'm developing Facebook JavaScript apps on a daily basis, but keep stumbling into some code snippets I don't understand, on the Facebook Documentation, and other websites I visit.

I searched Google for CURL, and found some descriptions about it. I can't figure out how Facebook wants me to use it.

```
curl -F "title=Example Title" -F "description=Description" \
-F "start_time=1329417443" \
"https://graph.facebook.com/PAGE_ID/milestones?access_token=_"

```

It's nonsens for me. Can you help me understand in what context I can use it for Facebook , and maybe in general, and guide me in the right direction where to find more on the subject?
