Reconcile vim swap files

README.md

Vim creates temporary files with the *.swp extension when editing files; if the session is terminated or the computer reboots/crashes etc without cleanly exiting, these stick around.

This script seqarches for such files, and allows the user to use vim to check that the file actually has the latest changes from the swap, then offers to delete the swap file.

The script uses bash builder syntax and inclusions, and can be run directly in bbrun. It can also be be built to a standalone script.

#
# Find temporary vim "swap" files, try to load them in a new session.
#
# After the user exits vim, they are asked whether to delete the swap file.
