 # pallet
 Platform Independent Tooling
+
+Provides support for various expressive idioms typical of scripting languages,
+with a goal of supporting portable code runnable in many environments with little or no customization.
+
+Target environments include Linux, OSX, Cygwin, Msys2, Mingw, WSL, Windows.
+
+Example script:
+```scala
+#!/usr/bin/env -S scala -cp target/scala-3.3.0/classes
+// hashbang line above is sufficient after 'sbt compile'
+import vastblue.pathextend.*
+
+def main(args: Array[String]): Unit = {
+  // show system memory info
+  for (line <- "/proc/meminfo".path.lines) {
+    printf("%s\n", line)
+  }
+  // list child directories of the current working directory
+  val cwd: Path = ".".path
+  for ( (p: Path) <- cwd.paths.filter { _.isDirectory }){
+    printf("%s\n", p.norm)
+  }
+}
+```
