# @brief Opens a file type with the appropriate program based on the mime-type
# @description
#   This script heavily borrows from [opener](https://github.com/Docbroke/shell_tools/blob/main/opener).
#   It makes some minor tweaks including linting fixes. It is configured
#   to properly work with [Gas Station](https://github.com/megabyte-labs/Gas-Station).
#   It is used to handle cross-VM links when Gas Station is used to provision [Qubes](https://www.qubes-os.org/).
#   When called with -d, the default program is used.

# Default to system open executable on macOS
if [ -d /Applications ] && [ -d /Library ]; then
