Welcome!
UPDATE: This list is no longer maintained. I've moved it to its own repo so you can send suggestions as Pull Requests. https://github.com/dideler/bootstrapping/
For feedback or suggestions, please send a tweet (@dideler). Gist comments don't notify me. Pull requests aren't possible with gists (yet), so I don't recommend forking because then I can't easily get the change.
Starring this gist will give me an idea of how many people consider this list useful.

| # Script to link in all your old SDKs every time you upgrade Xcode | |
| # Create a directory called /SDKs (or modify source_path). | |
| # Under it, put all the platform directories: | |
| # MacOSX.platform iPhoneOS.platform iPhoneSimulator.platform | |
| # Under those, store the SDKs: |
| Each existing unread and subsequent new emails after the script is started are | |
| passed as Mail objects to "process_email" function.Function header is provided | |
| but processing implementation is left to the user. Error logs are currently sent | |
| to a rotating log file (in the same directory as the script) and to STDOUT. | |
| Instead of polling or checking the server for new emails every now and then, | |
| IMAP IDLE check is utilized. Ensure that the IMAP server supports IDLE command | |
| and allows at least 5 minutes of idling*** and uses the default ports for this | |
| script to work. Tested to work with Gmail and default installations of MS | |
| Exchange Server. |
Most of programs will not accept an email using just @localhost as domain.
So, edit /etc/hosts file to make the domain localhost.com point to your machine, including this content to the file:
127.0.0.1 localhost.com
