Usage: ${0##*/} [FILES]

|
|
Convert non-ASCII characters to their ASCII equivalent. If no files are
|
|||
|
|
provided, use stdin.
|
|||
|
|
|
|||
|
|
Options:
|
|||
|
|
|
|||
|
|
-i: If files are provided, convert them in-place.

## Note that we also use 'sed -i' to edit files instead of 'ex'. Otherwise the
|
|||
|
|
## code looks ugly if we try to handle both stdin and files with only one
|
|||
|
|
## call. Besides, ex does not support multiple file editing.
