+/* Locate a member of an archive, given the path of the archive and the path
+ * of the desired member.
  *
  * Input:
  *     archive         Path to the archive
- *     member          Name of member. If it is a path, only the last
- *                     component is used.
+ *     member          Name of member; only its basename is used.
  *     hash            TRUE if archive should be hashed if not already so.
  *
  * Results:
- *     A pointer to the current struct ar_hdr structure for the member. Note
- *     That no position is returned, so this is not useful for touching
- *     archive members. This is mostly because we have no assurances that
- *     The archive will remain constant after we read all the headers, so
- *     there's not much point in remembering the position...

+ *     The ar_hdr for the member.
