+.coNP Macro @ in-package
+.synb
+.mets (in-package << name )
+.syne
+.desc
+The
+.code in-package
+macro causes the
+.code *package*
+special variable to take on the package denoted by
+.metn name .
+The macro checks, at expansion time, that
+.meta name
+is either a string or symbol. An error is thrown if
+this isn't the case.
+
+The
+.meta name
+argument expression isn't evaluated, and so must not be quoted.
+
+The code generated by the macro performs a search for the
+package; if the package is not found at the time when
+the macro's expansion is evaluated. An error is thrown if
+the package isn't found.
