SHORT DESCRIPTION
    Describes PSDocs Conventions including how to use and author them.
 
LONG DESCRIPTION
    PSDocs generates documents dynamically from input. When generating multiple
    documents it is often necessary to name or annotate them in a structured
    manner. Conventions achieve this by hooking into the pipeline to trigger
    custom actions defined in a script block.
 
    USING CONVENTIONS
    A convention once defined can be included by using the `-Convention`
    parameter of `Invoke-PSDocument`. To use a convention specify the name of
    the convention by name. For example:
 
    Invoke-PSDocument -Convention 'ExampleConvention';
 
    If multiple conventions are specified in an array, all are executed in they
    are specified. As a result, the convention specified last may override state
    set by earlier conventions.
 
    DEFINING CONVENTIONS
    To define a convention, add a `Export-PSDocumentConvention` block within a
    `.Doc.ps1` file. When executed the `.Doc.ps1` must be in an included path or
    module with `-Path` or `-Module`.
    The `Export-PSDocumentConvention` block works similar to the `Document`
    block. Each convention must have a unique name. For example:
 
    # Synopsis: An example convention.
    Export-PSDocumentConvention 'ExampleConvention' {
        # Add code here
    }
 
    BEGIN PROCESS END BLOCKS
    Conventions define three executable blocks `Begin`, `Process`, `End` similar
    to a PowerShell function. Each block is injected in a different part of the
    pipeline as follows:
    - `Begin` occurs before the document definition is called.
    - `Process` occurs directly after the document definition is called.
    - `End` occurs after all documents have been generated.
    Convention block limitations:
    - `Begin` can not use document specific variables such as `$Document`.
    - `End` can not use automatic variables except `$PSDocs.Output`.
    By default, the `Process` block used. For example:
 
    # Synopsis: The default { } executes the process block
    Export-PSDocumentConvention 'ExampleConvention' {
        # Process block
    }
     
    # Synopsis: With optional -Process parameter name
    Export-PSDocumentConvention 'ExampleConvention' -Process {
        # Process block
    }
 
    To use `Begin` or `End` explicitly add these blocks. For example:
 
    Export-PSDocumentConvention 'ExampleConvention' -Process {
        # Process block
    } -Begin {
        # Begin block
    } -End {
        # End block
    }
 
    NAMING DOCUMENTS
    Generated document output files are named based on InstanceName. To alter
    the InstanceName of a document use the `InstanceName` property.
    Syntax:
 
    $PSDocs.Document.InstanceName = value;
 
    For example:
 
    # Synopsis: An example naming convention.
    Export-PSDocumentConvention 'TestNamingConvention1' {
        $PSDocs.Document.InstanceName = 'NewName';
    }
 
    SETTING OUTPUT PATH
    Generated document output files are named based on OutputPath. To alter the
    OutputPath of a document use the `OutputPath` property.
    Syntax:
 
    $PSDocs.Document.OutputPath = value;
 
    For example:
 
    # Synopsis: An example naming convention.
    Export-PSDocumentConvention 'TestNamingConvention1' {
        $newPath = Join-Path -Path $PSDocs.Document.OutputPath -ChildPath 'new';
        $PSDocs.Document.OutputPath = $newPath;
    }
