-# multiconf.make
-
-**multiconf.make** is a self-contained Makefile include that lets you build the **same targets under many different flag sets**. For example debug vs release, ASan vs UBSan, GCC vs Clang.
-Each different set of flags generates object files into its own **dedicated cache directory**, so objects compiled with one configuration are never reused by another.
-Object files from previous configurations are preserved, so swapping back to a previous configuration only requires compiling objects which have actually changed.

-## Benefits at a glance
-
-| Benefit | What `multiconf.make` does |
-| --- | --- |
-| **Isolated configs** | Stores objects into `cachedObjs/<hash>/`, one directory per unique flag set. |
-| **Fast switching** | Reusing an old config is instant—link only, no recompilation. |
-| **Header deps** | Edits to headers trigger only needed rebuilds. |
-| **One-liner targets** | Macros (`c_program`, `cxx_program`, …) hide all rule boilerplate. |
-| **Parallel-ready** | Safe with `make -j`, no duplicate compiles of shared sources. |
-| **Controlled verbosity** | Default only lists objects, while `V=1` display full commands. |
-| **`clean` included** | `make clean` deletes all objects, binaries and links. |

-## Quick Start
-
-### 1 · List your sources
-
-```make
-C_SRCDIRS := src src/cdeps # all .c are in these directories
-CXX_SRCDIRS := src src/cxxdeps # all .cpp are in these directories
-```
-
-### 2 · Add and include
-
-```make
-# root/Makefile
-include multiconf.make
-```
-
-### 3 · Declare targets
-
-```make
-app:
-$(eval $(call c_program,app,app.o cdeps/obj.o))
-
-test:
-$(eval $(call cxx_program,test, test.o cxxdeps/objcxx.o))
-
-lib.a:
-$(eval $(call static_library,lib.a, lib.o cdeps/obj.o))
-
-lib.so:
-$(eval $(call c_dynamic_library,lib.so, lib.o cdeps/obj.o))
-```
-
-### 4 · Build any config you like
-
-```sh
-# Release with GCC
-make CFLAGS="-O3"
-
-# Debug with Clang + AddressSanitizer (new cache dir)
-make CC=clang CFLAGS="-g -O0 -fsanitize=address"
-
-# Switch back to GCC release (objects still valid, relink only)
-make CFLAGS="-O3"
-```
-
-Objects for each command live in different sub-folders; nothing overlaps.
