 9[`dte`](https://craigbarnes.gitlab.io/dte/) is an interesting editor I started
10using lately more and more. Since it is using
11[`execvp()`](https://linux.die.net/man/3/execvp) it can be easily extended. I
12needed comment/uncomment feature so I created a small utility that does this for
13me. Code lives on repository [dte
14extensions](https://git.mitjafelicijan.com/dte-extensions.git/about/) but this
15utilities can be used for whatever you want. Make sure you have version 1.11 or
16above.

18Next one will be invoking formatter based on the type of a file.
