Powershell: create multiple .txt from one .txt with filenames from string

I have no programming skills, yet a very specific task: I have to split one massive text-file into many, splitting them at a specific textmark (@). I decided to try Powershell script to accomplish this.

So far, that's what I have come up with:

InputFile = "c:\test.txt"
$Reader = New-Object System.IO.StreamReader($InputFile)
$a = 1
While (($Line = $Reader.ReadLine()) -ne $null) {
    If ($Line -match "@") {
        $OutputFile = "c:\splittedfile$a.txt"
        $a++
    }    
    Add-Content $OutputFile $Line
}

Now, what I want to achieve is not to simply base filenames on a loop. Instead, the second line of each new file is to act as filename, and I have no idea how to do this.

Edit @Jason Boyd: Specifying the structure of the file based on Jason's comment: It is basically a large template for a wiki, which is why the resulting textfiles need to have specific names (in the first example "buenos aires_audiencia_rpl". The number of lines is not constant, since "Comentario" may be pre-filled and have line breaks.

@
buenos aires_audiencia_rpl
======= Buenos Aires, Audiencia (RPL) ======= 
^Variantes | | 
===== Comentario =====

 ====  Geografía ====  
 ==== Historia institucional ==== 
 ====  Población y economía ==== 
 ==== Iglesia ==== 
 ====  Bibliografia ==== 
 ====  Citas textuales ====

You could read another line once your condition matches:

While (($Line = $Reader.ReadLine()) -ne $null) {
    If ($Line -match "@") {
        $OutputFile = $Reader.ReadLine()
        Add-Content $OutputFile $Line
        $Line = $OutputFile
        $a++
    }    
    Add-Content $OutputFile $Line
}
