[Qgis-developer] Field width when converting MID-MIF to SHP

Hi Dev,
I know this is more an OGR question, but rather than signing up to 
another list, I'm hoping someone here knows the answer.

I want to create _a lot_ of blank SHP files with schemas I currently 
have in CSV files.

(For me) the easiest way is to create a script that reads the CSV files 
and generates  empty (geometry wise) Mapinfo MID-MIF filesets.
I then use ogr2ogr to batch convert these into empty shapefiles that 
have the correct attribute schema.


In the MIF file I can say "character 36", or Decimal 6,0 or Real.
Can I get any reassurance that the resulting DBF file will contain the 
36 char length character field - If I look at the table in QGIS, I do 
not know how wide the attribute field is.
Likewise for integer and real data types I too need to nail down the 
field widths.
