## This file is designed to be sourced from a bash script whose name takes the
|
|
## form 'command-name'. This script will then instead invoke
|
|
## '[depot_tools]/command_name.py' correctly under mingw as well
|
|
## as posix-ey systems, passing along all other command line flags.
|
|
|
|
## Example:
|
|
## echo ". python_runner.sh" > git-foo-command
|
|
## ./git-foo-command #=> runs `python git_foo_command.py`
|
|
|

|
|
# path, but calling 'git-cl' results in a POSIX-style path), so don't assume a
|
|
# particular format.

# First try to split it using Windows format ...
