Brief description of tools/files: Gromacs installs a few GMXRC files alongside its binary in $GROMACS\_DIR/bin. By sourcing the appropriate file for your shell, the appropriate PATH variables (and a few Gromacs specific ones) are updated so that when running `gmx` the binary from that distribution is used.

This `GMXRC.fish` file implements that for the Fish shell.

Instructions:

1. Copy file to the `$GROMACS_DIR/bin` directory, where `$GROMACS_DIR` is your installation directory. This directory is where the `gmx` binary and the other `GMXRC` files are.
2. Source the file: `source $GROMACS_DIR/bin/GMXRC.fish`
3. Optionally: Inspect $PATH and Gromacs variables

```auto
echo $PATH
echo $GMXBIN

```

How the work has been tested/reviewed: Tested in Fish version 3.3.1. Like the standard `GMXRC` files, path variables are cleaned up if multiple `GMXRC.fish` files are sourced – only the most recently sourced file will be present in $PATH.
