[New App Request] TortoiseSVN (On Proposals list)

[AScott-WWF]

N.B. As TortoiseSVN files are hosted on SourceForge, a certain amount of URL manipulation needs to be carried out.
Also to ensure the files are served from different SourceForge mirrors, a list of Mirrors is contained in $SFMirrorList the mirror is randomly chosen into $SFMirror before generating the URLs - therefore each run of the script is likely to present different SourceForge domains to the file locations.

Script:

# Get-TortoiseSVN.ps1

# Define AppName
$AppName = "TortoiseSVN"

# Main script to fetch and process links
$ReleaseUrl = "https://tortoisesvn.net/downloads.html"
$InstallInstructionsUrl = "https://tortoisesvn.net/faq.html#uninstallfirst"

Write-Verbose "Obtaining $($AppName) Release Versions from $($ReleaseUrl)...`n"

$AppVersions = @(
        @{Architecture = 'x86'; Type = 'msi'; Pattern = 'Download TortoiseSVN \d+\.\d+\.\d+ - 32-bit, linked to SVN'; VersionPattern = 'TortoiseSVN-(\d+\.\d+\.\d+\.\d+)-'}
        @{Architecture = 'x64'; Type = 'msi'; Pattern = 'Download TortoiseSVN \d+\.\d+\.\d+ - 64-bit, linked to SVN'; VersionPattern = 'TortoiseSVN-(\d+\.\d+\.\d+\.\d+)-'}
