Comment(by matt.cottrell@…):

 Replying to [comment:12 ryandesign@…]:
 > Two of the things being made writeable (formerly using `system "chmod"`,
 now `file attributes`) are directories; fine; you want regular users to be
 able to put files into them. The third is a file called arb_tcp.dat, which
 lib/Makefile copies from arb_tcp_org.dat. This feels like a config file
 that the user is expected to edit; is that right? If so, we should not
 register the file to the port. Currently, any changes the user makes to
 this file are lost when they upgrade the port. Let me know and I can make
 these changes.

 That's right, arb_tcp.dat is a config file that will be edited by the
 user.  We need to preserve its contents and not overwrite it when the port
 is upgraded.  Likewise the files pts and macros should not be overwritten
 upon upgrading the port.

 Thanks for catching that one.
