0.1.2

• = are now allowed in filenames
• : are now allowed in filenames (Drake will default to local file system instead of issuing "invalid filesystem" error, i.e. bad:name -> file:bad:name)
• CLI changes:
• CLI is now getopt-compliant (i.e. one could do drake -aw my-workflow.d)
• -d doesn't work any more for debugging info: only --debug (-d reserved for future use)
• --debug prints much less info now, --trace added for more verbose output
• Added checking for conflicting options (i.e. --preview vs --print).
• Help is now printed nicely
• Added --step-delay to specify the amount of time, in milliseconds, to wait after each step. Should help with desynchronized filesystems.
• bugfixes: #34

0.1.1

• Drake now works with Drip which allows to bring down startup time essentially to zero in most cases.
• Added support for R ("R" protocol). See resources/regtest/regtest_interpreters.d for usage example.
