+.SYNOPSIS
+    Lists obsoletions, deprecations, and outdated dependencies for a Maven project.
+
+.DESCRIPTION
+    This script runs various Maven plugins to gather information about:
+    1. Code deprecations (calls to @Deprecated methods/classes).
+    2. Outdated dependencies (using versions-maven-plugin).
+    3. Outdated plugins (using versions-maven-plugin).
+    4. Unused declared dependencies (using maven-dependency-plugin).
+
+.PARAMETER IncludeTransitive
+    If set, includes transitive dependencies in the outdated dependencies report.
+
+.PARAMETER OnlyDeprecations
+    If set, only checks for code deprecations and skips dependency/plugin checks.
+
+.PARAMETER PomFile
+    Path to the pom.xml file. Defaults to "pom.xml" in the script's directory.
