"""
Split a log file into multiple files based on the dates at the start at each line.
For that time when logrotate did not run...
See the help text for more information on using this script.

Limitations:
- The date must be at the start of each line must have a fixed length. This could be made more flexible by e.g. allowing
  the user to provide a regex to match the date.

Script to get the first EntityDescriptor from a SAML 2.0 metadata file that has an IDPSSODescriptor with a shibmd:Scope
Extension with the specified value and return the EntityDescriptor as XML.

This allows you to get an EntityDescriptor for a identity provider from a large metadata file by the scope in its
EntityDescriptor.

This script uses XSLT to do the matching, so it can be easily modified to match on other criteria.

 * Because public key crypto is not suitable for arbitrary length data, encryption is done in two steps
 * 1. Generate a random symmetric key and encrypt the plaintext with that key

/** Making opaque values like GUIDs or session identifiers easier to compare and distinguish

 * By giving each opaque value a background color that is derived from the value itself, it
 * becomes much easier to eyeball whether two values are likely to be the same. This really helps

It is possible to use Dropbox as a "remote" repository. It is not perfect, updating or pushing to the remote from two location simultaniously will surely corrupt the repository. That being said it is a practical trick for syncing repositories between computers without both having write access to "origin" (i.e. github, gitlab or the like).

I store the repositories in a directory "git" in my dropbox folder. Create it if it does not yet exist, or make up you own name: mkdir ~/Dropbox/git/

1. Change to the repository for which you want to create a remote
