[netcdfgroup] Fortran appending a file as a global attribute

[Tim Hoar]

I am fairly well-versed with the F90 interface to netCDF, but the  
following problem
has me stumped.

My Fortran program has an input namelist (usually less than 100  
lines) that I would
like to insert into a netCDF file as a global attribute.

Any ideas?

At the risk of steering the discussion ...
The NetCDF Fortran 90 Interface Guide has a statement in Section 5.2  
"Attribute Conventions":

history
A global attribute for an audit trail. This is a character array with  
a line for each invocation of a program that has modified the  
dataset. Well-behaved generic netCDF applications should append a  
line containing: date, time of day, user name, program name and  
command arguments.

the key word being 'append' ...

Any ideas (short of "NF90_GET_ATT, NF90_DEL_ATT, [append],  
NF90_PUT_ATT" for each line in the file)
would be appreciated.
