    .DESCRIPTION
    Replace Unix paths in Synctex (Latex) file with Windows paths.
    This script un-gzips the Synctex.gz file, replaces Unix paths set by Docker image arara-docker
    with a Windows path of choice. The paths are defined by parameters.

    .PARAMETER SynctexFile
    Path to the Synctex file to be manipulated.

    .PARAMETER LatexInstallLocation
    Path to your LateX installation that will be used to replace the old Unix paths

    .INPUTS
    None. You cannot pipe objects to Fix-Syntex.ps1

    .OUTPUTS
    Re-writes existing Synctex file with replaced content.

    .EXAMPLE
    PS> Fix-Synctex.ps1 -SynctexFile C:\MyLatexSrc\build\document.synctex.gz -LatexInstallLocation "C:\Program Files\MyLatexInstallation"
