**Basic Overview**
This is a lightweight/dependency free C build system built entirely around standard POSIX tools. It introduces a python style virtual environment for your C projects using a simple shell script. It tracks your compiler, linker flags, and build options in a local state file without needing cmake or other heavy build generators.

**Example Use**
To get started with a fresh project create your directory and run the initialization command.

`make init`

Next activate your virtual environment by sourcing the configuration script into your current shell session.

`. config/activate` (or `source config/activate`) the former is simply POSIX compliant.

Once you are inside the environment you can run your builds and clean up whenever you want.

`make debug`
`make build`
`make release`
`make clean`

**What Each Build Target Does**

* init sets up the required folder structure and generates the activation script
* debug compiles your code with debug symbols enabled and optimization turned off
* build compiles your code for regular development use using your custom flags
* release updates the internal version timestamp and compiles an optimized production binary
* clean removes all intermediate object files and generated makefiles

**Example env_set Commands**
You can adjust your toolchain and compiler options dynamically using the `env_set` function while the environment is active.


Example uses:
```
env_set CC cc
env_set CFLAGS -std=c17 -pedantic -Wall -Wextra
env_set DEBUG_FLAGS -g3 -O0
env_set RELEASE_FLAGS -O2 -DNDEBUG
env_set LIBS -lm
```
