### [Build.zsh][build.zsh]: makefile creation. <side-note>*for mere mortals*</side-note>
A `Makefile` is very useful to share your project, <u>whatever your project is</u>, no matter if it is an application, a library, the language used, etc.
A `Makefile` is very useful to share your project, <u>whatever your project is</u>.
No matter if it is an application or a library, whatever the language used, etc.
Build.zsh creates a makefile from a simple declarative configuration file.
A `Makefile` should:
- **compile and link the application**
- **handle dependencies** and **rebuild only updated parts of the application** *for incremental builds*
- **allow users to rebuid any part of your project independently**
- **handle dependencies** and **rebuild only the updated parts of the application** *for incremental builds*
- **allow users to rebuild any part of the project independently**
- **install the application**<br />
The default installation root directory is `/usr/local` but you should be able to change that easily (with an environment variable or through configuration).

- **create a tarball of the project**<br />
This tarball includes your application, its man-pages, the Makefile to build it, etc.

Now you do not have any good reason avoiding Makefiles for your projects!
***But, I don't like Makefiles!***<br />
You like the functionalities we presented here, but you want an alternative to the Makefile?
