+.meIP >> --in-package= name
+This option changes to the specified package, by finding the package of the
+specified
+.meta name
+and assigning that to the
+.code *package*
+special variable. If the package is not found, a diagnostic is issued,
+and \*(TX terminates unsuccessfully.
+The package thus specified is visible to the subsequent occurrences of the
+.code -e
+family of options as well as of the
+.code --compile
+option. It does not affect the value of

+If

+.code compile-update-file
+as the target argument; otherwise, that argument is defaulted.

+\*(TX to terminate abnormally. Similarly to the
