  * To use functions for a specific path style regardless of the current OS
  * import the modules from the platform sub directory instead.
  *
- * Example, for POSIX:
+ * ## Basic Path Operations
+ *
+ * ```ts
+ * import * as path from "@std/path";
+ * import { assertEquals } from "@std/assert";
+ *
+ * // Get components of a path
+ * if (Deno.build.os === "windows") {
+ *   assertEquals(path.basename("C:\\Users\\user\\file.txt"), "file.txt");
+ *   assertEquals(path.dirname("C:\\Users\\user\\file.txt"), "C:\\Users\\user");
+ *   assertEquals(path.extname("C:\\Users\\user\\file.txt"), ".txt");
+ * } else {
+ *   assertEquals(path.basename("/home/user/file.txt"), "file.txt");
+ *   assertEquals(path.dirname("/home/user/file.txt"), "/home/user");
+ *   assertEquals(path.extname("/home/user/file.txt"), ".txt");
+ * }
+ *
+ * // Join path segments
+ * if (Deno.build.os === "windows") {

+ * } else {
+ *   assertEquals(path.join("/home", "user", "docs", "file.txt"), "/home/user/docs/file.txt");
+ * }
+ *
+ * // Normalize a path
+ * if (Deno.build.os === "windows") {
+ *   assertEquals(path.normalize("C:\\Users\\user\\..\\temp\\.\\file.txt"), "C:\\Users\\temp\\file.txt");
+ * } else {
+ *   assertEquals(path.normalize("/home/user/../temp/./file.txt"), "/home/temp/file.txt");
+ * }
+ *
+ * // Resolve absolute path
+ * if (Deno.build.os === "windows") {
+ *   const resolved = path.resolve("C:\\foo", "docs", "file.txt");
+ *   assertEquals(resolved, "C:\\foo\\docs\\file.txt");
+ *   assertEquals(path.isAbsolute(resolved), true);
+ * } else {

+ *   assertEquals(resolved, "/foo/docs/file.txt");
+ *   assertEquals(path.isAbsolute(resolved), true);
+ * }
+ *
+ * // Get relative path
+ * if (Deno.build.os === "windows") {
+ *   assertEquals(path.relative("C:\\Users", "C:\\Users\\docs\\file.txt"), "docs\\file.txt");
+ *   assertEquals(path.relative("C:\\Users", "D:\\Programs"), "D:\\Programs");

+ *   assertEquals(path.relative("/home/user", "/var/data"), "../../var/data");
+ * }
+ * ```
+ *
+ * ## Path Parsing and Formatting
+ *
+ * ```ts
+ * import * as path from "@std/path";
+ * import { assertEquals } from "@std/assert";
+ *
+ * if (Deno.build.os === "windows") {
+ *   const parsedWindows = path.parse("C:\\Users\\user\\file.txt");
+ *   assertEquals(parsedWindows.root, "C:\\");
+ *   assertEquals(parsedWindows.dir, "C:\\Users\\user");
+ *   assertEquals(parsedWindows.base, "file.txt");
+ *   assertEquals(parsedWindows.ext, ".txt");
+ *   assertEquals(parsedWindows.name, "file");
+ *
+ *   // Format path from components (Windows)
+ *   assertEquals(
+ *     path.format({ dir: "C:\\Users\\user", base: "file.txt" }),
+ *     "C:\\Users\\user\\file.txt"
+ *   );
+ * } else {
+ *   const parsedPosix = path.parse("/home/user/file.txt");
+ *   assertEquals(parsedPosix.root, "/");
+ *   assertEquals(parsedPosix.dir, "/home/user");
+ *   assertEquals(parsedPosix.base, "file.txt");
+ *   assertEquals(parsedPosix.ext, ".txt");
+ *   assertEquals(parsedPosix.name, "file");
+ *
+ *   // Format path from components (POSIX)
+ *   assertEquals(
+ *     path.format({ dir: "/home/user", base: "file.txt" }),
+ *     "/home/user/file.txt"
+ *   );
+ * }
+ * ```
+ *
+ * ## URL Conversion
+ *
+ * ```ts
+ * import * as path from "@std/path";
+ * import { assertEquals } from "@std/assert";
+ *
+ * // Convert between file URLs and paths
+ * if (Deno.build.os === "windows") {
+ *   assertEquals(path.fromFileUrl("file:///C:/Users/user/file.txt"), "C:\\Users\\user\\file.txt");
+ *   assertEquals(path.toFileUrl("C:\\Users\\user\\file.txt").href, "file:///C:/Users/user/file.txt");
+ * } else {
+ *   assertEquals(path.fromFileUrl("file:///home/user/file.txt"), "/home/user/file.txt");
+ *   assertEquals(path.toFileUrl("/home/user/file.txt").href, "file:///home/user/file.txt");
+ * }
+ * ```
+ *
+ * ## Path Properties
+ *
+ * ```ts
+ * import * as path from "@std/path";
+ * import { assertEquals } from "@std/assert";
+ *
+ * // Check if path is absolute
+ * if (Deno.build.os === "windows") {
+ *   assertEquals(path.isAbsolute("C:\\Users"), true);
+ *   assertEquals(path.isAbsolute("\\\\Server\\share"), true);
+ *   assertEquals(path.isAbsolute("C:relative\\path"), false);
+ *   assertEquals(path.isAbsolute("..\\relative\\path"), false);
+ * } else {
+ *   assertEquals(path.isAbsolute("/home/user"), true);
+ *   assertEquals(path.isAbsolute("./relative/path"), false);
+ *   assertEquals(path.isAbsolute("../relative/path"), false);
+ * }
+ *
+ * // Convert to namespaced path (Windows-specific)
+ * if (Deno.build.os === "windows") {
+ *   assertEquals(path.toNamespacedPath("C:\\Users\\file.txt"), "\\\\?\\C:\\Users\\file.txt");
+ *   assertEquals(path.toNamespacedPath("\\\\server\\share\\file.txt"), "\\\\?\\UNC\\server\\share\\file.txt");
+ * } else {
+ *   // On POSIX, toNamespacedPath returns the path unchanged
+ *   assertEquals(path.toNamespacedPath("/home/user/file.txt"), "/home/user/file.txt");
+ * }
+ * ```
+ *
+ * ## Glob Pattern Utilities
+ *
+ * ```ts
+ * import * as path from "@std/path";
+ * import { assertEquals } from "@std/assert";
+ *
+ * // Check if a string is a glob pattern
+ * assertEquals(path.isGlob("*.txt"), true);
+ *
+ * // Convert glob pattern to RegExp
+ * const pattern = path.globToRegExp("*.txt");
+ * assertEquals(pattern.test("file.txt"), true);
+ *
+ * // Join multiple glob patterns
+ * if (Deno.build.os === "windows") {
+ *   assertEquals(path.joinGlobs(["src", "**\\*.ts"]), "src\\**\\*.ts");
+ * } else {
+ *   assertEquals(path.joinGlobs(["src", "**\/*.ts"]), "src/**\/*.ts");
+ * }
+ *
+ * // Normalize a glob pattern
+ * if (Deno.build.os === "windows") {

+ * } else {
