[BioC] Import sequences from MacClade 4.*

[Brian]

Hello List,
sorry if this is a stupid question, but I am returning some old 
sequences that I have laying around, the program is a mac program called 
MacClade, but the sequence file looks like:

#NEXUS
[MacClade 4.03 registered to University]


BEGIN DATA;
     DIMENSIONS  NTAX=53 NCHAR=673;
     FORMAT DATATYPE=DNA  MISSING=? GAP=-  INTERLEAVE ;
MATRIX

[                 10        20        30        40        50        60]
[                 .         .         .         .         .         .]

Does this look familiar to anyone? Did I overlook some function in the 
"seqinr" package? Before I write some function to get the sequences out 
for me.

Thanks for the help!

Cheers,
Brian
