A Tool to Create ASCII Tables

I needed an ASCII table in a LaTeX document. I wasn’t sure how large it should be or how many columns it should have, so it should be easily customizable. So I hacked together a little command line tool that creates .tex files for ASCII tables. That’s it. Written in C.
The tool offers some options:
./ascii --help
Usage: ascii [OPTION…] A minimal tool to generate .tex code for ASCII tables

-D, --dlabel=STRING Modify the decimal label
-e, --end=n Character code to end with
-h, --hex Only create the hexadecimal column
-H, --hlabel=STRING Modify the hexadecimal label
-o, --output=FILE Output filename, default is ascii.tex
-s, --start=n Character code to start with
-w, --wrap=n Number of lines before the table wraps to the next
column
