This script is meant to help with managing the LATEST file. Usage:
|
|
|
|
$0 snapshot SHA
|
|
Updates the LATEST file to point to the given SHA (which must be a
|
|
valid git reference to a commit on origin/master). If the current
|
|
version defined in LATEST is already a snapshot, keeps the stable part
|
|
of the version unchanged; otherwise, increments the patch number.
|
|
|
|
Any other invocation will display this help message.
|
|
|
|
Note: at the moment, changing the version string for a stable release is left
|
|
as a manual exercice, but that may change in the future.
