 function Find-PSMDType
 {
+<#
+	.SYNOPSIS
+		Searches assemblies for types.
+	
+	.DESCRIPTION
+		This function searches the currently imported assemblies for a specific type.
+		It is not inherently limited to public types however, and can search interna just as well.
+	
+		Can be used to scan for dependencies, to figure out what libraries one needs for a given type and what dependencies exist.
+	
+	.PARAMETER Name
+		Default: "*"
+		The name of the type to search for.
+		Accepts wildcards.
+	
+	.PARAMETER FullName
+		Default: "*"
+		The FullName of the type to search for.
+		Accepts wildcards.
+	
+	.PARAMETER Assembly
+		Default: (Get-PSMDAssembly)
+		The assemblies to search. By default, all loaded assemblies are searched.
+	
+	.PARAMETER Public
+		Whether the type to find must be public.
+	
+	.PARAMETER Enum
+		Whether the type to find must be an enumeration.
+	
+	.PARAMETER Implements
+		Whether the type to find must implement this interface
+	
+	.PARAMETER InheritsFrom
+		The type must directly inherit from this type.
+		Accepts wildcards.
+	
+	.EXAMPLE
+		Find-PSMDType -Name "*String*"
+	
+		Finds all types whose name includes the word "String"
+		(This will be quite a few)
+	
+	.EXAMPLE
+		Find-PSMDType -InheritsFrom System.Management.Automation.Runspaces.Runspace
+	
+		Finds all types that inherit from the Runspace class
