 #      pkg_path -- canonicalize directories into "package paths"
 #
 # SYNOPSIS
-#      pkg_path dir ...
+#      pkg_path [-s pkgsrcdir] dir ...
+#
+# OPTIONS
+#      The following command line arguments are supported.
+#
+#      -s pkgsrcdir    Use the specified directory as the path to the
+#                      pkgsrc directory tree.  By default, this is the
+#                      value stored in the PKGSRCDIR environment variable.
 #
 # DESCRIPTION
 #      pkg_path canonicalizes the specified directories into package
 #      paths are are relative to the pkgsrc directory tree, and prints
-#      each of them to standard output on a new line.  Directories
-#      that are not valid package directories or are not found are
-#      skipped during processing.
+#      each of them to standard output on a new line.  The specified
+#      directories are taken to be relative to the current directory or
+#      are otherwise absolute paths.  Directories that are not valid
+#      package directories or are not found are skipped during processing.
 #
 # ENVIRONMENT
 #      PKGSRCDIR       This is the location of the pkgsrc directory tree,
