| Unfortunate name collision with the macOS/iOS note taking app

| Actually it does diagrams, sequence and flowchart. Sadly, the

| years and the developer has stopped responding to bug reports
| for at least a year. It's abandonware at this point.

| quiver is great. Basically Mac's Notes but for programmers.

| This looks like a really nice and well-made tool. Kudos and
| thanks for open sourcing!
|
| One nitpick: Why do you use a Makefile without using any of the
| features of Make and then even requiring a special GNUMake
| feature to make things work like a shell script? Why not simply
| provide shell scripts in the first place?
| gnulinux wrote:
| I do this too, my reasons are:
|
| * It's an old habit, I'm used to handwriting my own Makefiles
| for every project, and every time I start a new project it's an
| instinct to create a .gitignore and Makefile
|
| * There is always a possibility of needing make features in the
| future. Like nowadays my makefiles have `make build` recipe
| which builds docker containers via docker-compose and a `make
| run` that depends on `build` and then shells into that
| container.
|
| * make is easier to use than shell scripts since you can just
| do `make <cmd>` to run your command

| Thanks! I use a Makefile simply because someone else

| way, I'd be happy to receive a pull request to change it!

| I'm happy to see people are interested in the editor!

| Let me also point out that I wrote a short blog post about the
| motivation behind quiver, as well as some of its key features,
