# sync-push.sh — Export new commits as a git bundle to the shared folder.

# Usage: ./sync-push.sh [<share-dir>]

|
# Default share dir: $SYNC_SHARE or ~/fifiletrans
|

#
|
|
# On first run: creates a full bundle of all branches.
|
|
# On subsequent runs: creates an incremental bundle (only new commits).
|
|
# Checkpoint per branch is stored in git config: sync.exported.<branch>
