    .SYNOPSIS
        Bash Language Definition
    .DESCRIPTION
        Defines Bash within PipeScript.

        This allows Rust to be templated.

        Heredocs named PipeScript{} will be treated as blocks of PipeScript.

        ```bash
        <<PipeScript{}
        
        # This will be considered PipeScript / PowerShell, and will return the contents of a bash script.

        PipeScript{}
        ```
    .EXAMPLE
        Invoke-PipeScript {
            $bashScript = '
            echo ''hello world''

            <<PipeScript{}
                "echo ''$(''hi'',''yo'',''sup'' | Get-Random)''"
            PipeScript{}
        '
        
            [OutputFile('.\HelloWorld.ps1.sh')]$bashScript
        }

        Invoke-PipeScript .\HelloWorld.ps1.sh
