+# Origins
+**pico-c** is a project created by Zik at [https://code.google.com/p/picoc](https://code.google.com/p/picoc/ "Google code").
+The projet is now hosted at [https://gitlab.com/zsaleeba/picoc](https://gitlab.com/zsaleeba/picoc/ "Github.com"). 
+
+**pico-c** intends to be a very light **C** interpreter. **pico-c** is very small, but include many standard libraries.
+
+# The content
+Initially those libraries were natively integrated into pico-c:
+
+* ctype.h
+* errno.h
+* math.h
+* stdbool.h
+* stdio.h
+* stdlib.h
+* string.h
+* time.h
+* unistd.h
+
+Some of them were improved:
+
+* stdio.h
+* unistd.h
+
+We have planned to add support for 3 other useful libraries:
+
+* dirent.h
+* regex.h
+* socket.h
+* stat.h
+
+# The pico-c syntax
+
+```
+$ pico-c -h
+pico-c.exe, A very small C interpreter
+Usage: pico-c.exe [-h] [-i] [-m] [-n] [-o] [<filename1>...] [- <arg1>...]
+        -h: this help message
+        -i: force interactive mode at the end of scripts
+        -m: run main() function automaticaly
+        -n: don't print prompt
+        -o: the original "old" mode
+        -v: print version
+Exemples:
+        pico-c.exe script1.pcc script2.pcc
+        pico-c.exe -i script.pcc
+        pico-c.exe -m script1.pcc script2.pcc - arg1 agr2}
+```

+picoc
+-----
+
+PicoC is a very small C interpreter for scripting. It was originally written 
+as a script language for a UAV's on-board flight system. It's also very 
+suitable for other robotic, embedded and non-embedded applications.
+
+The core C source code is around 3500 lines of code. It's not intended to be 
+a complete implementation of ISO C but it has all the essentials. When 
+compiled it only takes a few k of code space and is also very sparing of 
+data space. This means it can work well in small embedded devices. It's also 
+a fun example of how to create a very small language implementation while 
+still keeping the code readable.
+
+picoc is now feature frozen. Since it's important that it remain small it's 
+intended that no more major features will be added from now on. It's been 
+tested on x86-32, x86-64, powerpc, arm, ultrasparc, HP-PA and blackfin 
+processors and is easy to port to new targets. 
+
+
+Compiling picoc
+---------------
+
+picoc can be compiled for a UNIX/Linux/POSIX host by typing "make".
+
+The test suite can be run by typing "make test".
+
+
+Porting picoc
+-------------
+
+platform.h is where you select your platform type and specify the includes 
+etc. for your platform.
+
+platform_XXX.c contains support functions so the compiler can work on 
+your platform, such as how to write characters to the console etc..
+
+platform_library.c contains your library of functions you want to make 
+available to user programs.
+
+There's also a clibrary.c which contains user library functions like 
+printf() which are platform-independent.
+
+Porting the system will involve setting up suitable includes and defines 
+in platform.h, writing some I/O routines in platform_XXX.c, putting 
+whatever user functions you want in platform_library.c and then changing 
+the main program in picoc.c to whatever you need to do to get programs 
+into the system.
+
+platform.h is set to UNIX_HOST by default so tests can be easily run on
+a UNIX system. You'll need to specify your own host setup dependent on 
+your target platform.
