+# C Libraries Function Indexer
+
+This project aims to index functions from the multiple implementations of the standard C libraries, and 
+for any of them show in which implementation or standard they can be found.
+
+Examples of covered standards are : C99, C11, SuSv2, SuSv4
+Examples of covered implementations are : glibc, uClibc-ng, FreeBSD libc
+
+The goal would be to index all standard functions, GNU extensions, BSD extensions at least.
+This way, when wondering if the function is GNU/BSD or standard, one could just look it up in the
+database and even see wether the extension is adopted (i.e. present in other implementations) or not.
+
+This repository contains the tools used to generate a json database of functions.
+
+## Using the database
+
+The database can be accessed via the web hosted implementation [here]().
+It was generated on my personal computer, using virtual machines.
+
+## Generating a database
+
+Generation can only be done under linux-glibc, and it assumes that `/bin/sh` is `bash`.
+You will need multiple tests systems (either physical computers or virtual machines)
+to index the bsds, macos, windows implementations.
+
+The main script should tell you everything you need :
+
+```
+chmod +x main.sh index.sh getlib.sh merge.sh # Add execution rights if needed
+./main.sh
+```
+
+## Internal organization
+
+- main.sh :
+    The main script. Checks for library/std installations, runs the indexer, and asks the user to run it on different systems.
+- index.sh :
+    The core of the project : index functions from different libcs, check for standards. Can be run in 'local system' mode.
+- index-win.bat :
+    The 'local system' version of the indexer, for Windows.
+- getlib.sh :
+    A script to obtain (download, configure, compile, install) all tested libc (glibc, uClibc-ng, ...) under the ./libs directory.
+- merge.sh :
+    A script to merge outputs (i.e. indexer output and local indexer output on freebsd), used to obtain final outputs.
+- merge-bigjson.sh
+    A script to merge all headers json files into one big json file.
+
+## TODO
+
+- Generate "stdh.sh" automatically, including : Cstd, SuS, GNU exts, BSD exts
+- MacOS indexer
+- Windows indexer (WIP, need stdh generator to generate powershell arrays....)
+
