New description:

 Presently, when launching Mame, the user is presented with several
 warnings:

 {{{
 $ mame
 Unable to create history.db

 Unable to create history.db
 }}}

 This is due to the default Mame configuration, which references read-only
 directories within the MacPorts tree.

 For the next port release, we should improve on this:
 * At a minimum, the port notes should mention that a custom user
 configuration file (.ini) will fix such issues.
 * In addition, it would be helpful to provide an example user
 configuration file.
 * And finally, it might also be worth using a default configuration, that
 references user-writable areas. Say, ~/Library/Application Support/Mame/

 Another consideration, is the Mame tools:
 * Currently, no soft links are created in ${prefix}/bin, for those
 additions.
 * For the next release, we should consider creating those... perhaps with
 a variant option to enable/disable.
 * To avoid possible clashes, consider adding a 'mame-' prefix to said
 links. (But need to verify that no issues are caused by that. For example,
 if any tool invokes another... that could be problematic. Net-Net, more
 testing/verification/investigation needed beforehand.)
