+# libcargs - command line argument library for C/C++
+This is a lighweight C command line argument library. It is currently compiled and
+tested under **Windows**, **MacOS** and **Linux**.
+
+## Features
+Please have a look at the
+**[reference](https://likle.github.io/cargs/reference/)** for detailed
+information. Some features this library includes:
+
+ * **cross-platform** on windows, linux and macOS
+ * **simple interface** - just one header
+ * **one simple loop** - to iterate over the arguments
+ * **automatic help output** - showing all options available
+ * **long and short options** - giving users alternatives
+ * **option values** - for options which are more than just flags
+
+ ## Building
+ **[Building](https://likle.github.io/cargs/build.html)**,
+ **[embedding](https://likle.github.io/cargs/embed.html)** and
+ **[testing](https://likle.github.io/cargs/build.html)** instructions are
+ available in the documentation (it's very easy).
+
+ ## Docs
+ All the documentation is available in the
+ **[the github page](https://likle.github.io/cargs/)** of this repository.
+
+ ## Example
+ ```c
+#include <cargs.h>
+#include <stdbool.h>
+#include <stdlib.h>

+
+### Example output
+```console
+foo@bar:~$ ./cargsdemo
+simple_flag: 0, multiple_flag: 0, long_flag: 0, key: -
+```
+
+```console
+foo@bar:~$ ./cargsdemo -k=test -sm --long
+simple_flag: 1, multiple_flag: 1, long_flag: 1, key: test
+```
+
+```console
+foo@bar:~$ ./cargsdemo --help
+Usage: cargsdemo [OPTION]...
+Demonstrates the cargs library.
+
+ -s Simple flag
+ -m, -M, -o, -O Multiple access letters
+ --long Long parameter name
+ -k, --key=VALUE Parameter value
+ -h, --help Shows the command help

+Fetches an option from the argument list.
+
+## Description
+```c
+bool cag_option_fetch(cag_option_context *context);
+```
+
+This function fetches a single option from the argument list. The context
+will be moved to that item. Information can be extracted from the context
+after the item has been fetched.
+The arguments will be re-ordered, which means that non-option arguments will
+be moved to the end of the argument list. After all options have been
+fetched, all non-option arguments will be positioned after the index of
+the context.
+
+## Parameters
+ * **context**: The context from which we will fetch the option.
+
+## Return Value
+Returns true if there was another option or false if the end is reached.
+

+This function gets the index within the argv arguments of the context. The

+non-option arguments after option fetching has finished.

+ * @brief Gets the current index of the context.
+ *
+ * This function gets the index within the argv arguments of the context. The

+ * particularly useful to inspect the original argument array, or to get
+ * non-option arguments after option fetching has finished.
+ *
+ * @param context The context from which the option was fetched.
+ * @return Returns the current index of the context.
