|
## Description
|
||
|
|
|
||
|
|
Presented with a series of lines on standard input, the program will
|
||
|
|
print an expression on standard output that denotes the line strings
|
||
|
|
in a syntax described in <https://tk-sls.de/wp/6071>.
|
||
|
|
|
||
|
|
The expression is suitable for Bourne Again Shell brace expansion.
