+    <summary>Extension package to provide compatibility with older versions of Chocolatey</summary>
+    <description><![CDATA[
+This package provides helper functions that re-introduces helpers that was removed or updated
+in Chocolatey, as well as helpers that is not available in older version of Chocolatey CLI.
+The purpose of the package is to allow older packages to keep functioning even on later versions
+of Chocolatey CLI where certain helpers have been removed.
+
+The helpers included in this package may not have any logic to handle the functionality to keep
+existing, but rather to ensure that packages using the helpers do not stop working.
+
+**WARNING: Do NOT use helper located in this package for removed functionality, unless absolutely necessary!**]]></description>

+<#
+.SYNOPSIS
+    Retrieve registry key(s) for system-installed applications from an exact or wildcard search.
+
+.DESCRIPTION
+    This function will attempt to retrieve a matching registry key for an already installed application,
+    usually to be used with a chocolateyUninstall.ps1 automation script.
+
+    The function also prevents `Get-ItemProperty` from failing when handling wrongly encoded registry keys.
+
+.PARAMETER SoftwareName
+    Part or all of the Display Name as you see it in Programs and Features.
+    It should be enough to be unique.
+    The syntax follows the rules of the PowerShell `-like` operator, so the `*` character is interpreted
+    as a wildcard, which matches any (zero or more) characters.
+
+    If the display name contains a version number, such as "Launchy (2.5)", it is recommended you use a
+    fuzzy search `"Launchy (*)"` (the wildcard `*`) so if Launchy auto-updates or is updated outside
+    of chocolatey, the uninstall script will not fail.
+
+    Take care not to abuse fuzzy/glob pattern searches. Be conscious of programs that may have shared
+    or common root words to prevent overmatching. For example, "SketchUp*" would match two keys with software
+    names "SketchUp 2016" and "SketchUp Viewer" that are different programs released by the same company.
+
+.PARAMETER IgnoredArguments
+    Allows splatting with arguments that do not apply and future expansion. Do not use directly.
+
+.INPUTS
+    System.String
+
+.OUTPUTS
+    PSCustomObject
+
+.EXAMPLE
+    [array]$key = Get-UninstallRegistryKey -SoftwareName "VLC media player"
+    $key.UninstallString
+
+    Exact match: software name in Programs and Features is "VLC media player"
+
+.EXAMPLE
+    [array]$key = Get-UninstallRegistryKey -SoftwareName "Gpg4win (*)"
+    $key.UninstallString
+
+    Version match: software name is "Gpg4Win (2.3.0)"
+
+.EXAMPLE
+    [array]$key = Get-UninstallRegistryKey -SoftwareName "SketchUp [0-9]*"
+    $key.UninstallString
+
+    Version match: software name is "SketchUp 2016"
+    Note that the similar software name "SketchUp Viewer" would not be matched.
