This is a compiled list of falsehoods programmers tend to believe about working with time.
Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

| # ----------------------------------------------------------------------------- | |
| # Syntax: | |
| # $0 {planKey} | |
| # ----------------------------------------------------------------------------- | |
| # Purpose: Bamboo does not automatically delete plan branches when the | |
| # corresponding branch in the repository gets deleted. Because Bamboo fails | |
| # to pull from it, it disables the branch but keep it around forever. | |
| # This script goes through all branches of a build plan and delete the ones |
| // You will need the VFS plugin | |
