+.SYNOPSIS
+    TOML Inline PipeScript Transpiler.
+.DESCRIPTION
+    Transpiles TOML with Inline PipeScript into TOML.
+
+    Because TOML does not support comment blocks, PipeScript can be written inline inside of specialized Multiline string
+
+    PipeScript can be included in a TOML string that starts and ends with ```{}```, for example ```"""{}"""```
+.Example
+    .> {
+        $tomlContent = @'
+[seed]
+RandomNumber = """{Get-Random}"""
+'@
+        [OutputFile('.\RandomExample.ps1.toml')]$tomlContent
+    }
