ABOUT THIS SCRIPT:

Import CSV data files as tables into Scribus

1. Create any frame of any size on your page but positioned 
where you want the table to be located (upper left corner)

2. Make sure it is selected

3. Execute this script:

You will be prompted first for the width of the left column in mm,
then the right column in mm, then height of all cells, and finally
for a csv filename

4. The data from the csv file will be imported and a table of
textboxes will be drawn on the page.

LIMITATIONS:

1. You are limited to two-column CSV data in your file.

2. In Scribus versions 1.3.5svn, when the script ends, you cannot
adjust text, colors, and line features for a group, whereas in 1.3.3.x,
all of these can be done without ungrouping.

HINTS:

Postgresql:
You can easily create a CSV file with a Postgresql database. From Postgresql,
toggle unaligned output with the '\a' switch, then activate a comma as
a separator with '\f ,' (without apostrophes). Send output to a file
with '\o myfile.csv', then query your database.

Sqlite3:
You can use "sqlite3 -csv" in the command line or ".mode csv" in sqlite's
interactive shell.
