+Library:
 
-stdint.h:
-*   Implement 7.20.3
-
-stdio.h:
-*   The only reason to keep a linked list of all streams is to make sure they
-    are flushed after main() returns. I wonder if only remembering the files
-    with a buffer would increase performance.
-*   Formatted scan
-*   %s precision should specify how much characters to *write*
-*   %s check for NULL
-*   %Ls this is an actual weird territory. If (wchar_t *) is a unicode string
-    then to determine it's "width" (to figure out field padding) would require
-    to use a Unicode composition algorithm. But the problem is that windows
-    Unicode rendering advances text by 2 units, even if it's 1 graphical
-    character that was composed from 2 unicode characters. The question
-    becomes: do we implement the thing correctly by using a more complex
-    solution, or do we succumb to windows' bullshittery. I guess the answer is
-    obvious. That's why I wrote this todo item :D
-*   tmpfile
-*   tmpnam
-*   tmpfile_s
-*   tmpnam_s
-*   Printing 8.98846567431157854073e+307
-*   Printing negative zero
-*   Add functions for testing a file path, creating directories
-*   Fix the bug where if a file wasn't closed the thing crashes when
-    trying to flush the buffer
-
-stdlib.h:
-*   Strtod base 16 must be correctly rounded
-*   Multibyte string functions
-*   Better PRNG
-*   Fix aligned_malloc
-*   Constraint Handlers
-*   getenv_s
-*   aligned_alloc can't be used with free()
-
-string.h:
-*   strnlen_s
-*   memset_s
-*   memmove_s
-*   memcpy_s
-*   strncpy_s
-*   strcpy_s
-*   strcat_s
-*   strncat_s
-*   strtok_s
-*   strerror_s
-*   strerrorlen_s
-
-tgmath.h:
-*   Due to the use of conditional operator in type-generic macros the
-    expression always expands to the value of type `long double`. This leads
-    to warnings when used with printf, e.g. as in printf("%f\n", exp(0)).
-    Using _Generic macros isn't a good choice either, because it won't work
-    with typedef'd types.
-    In other words there's no pure-C way to do tgmath.h.
-    That's probably the reason msvc stdlib headers don't implement tgmath.h.
-    clang implements it with __attribute__((__overloadable__)).
-
-threads.h:
-*   TODO: add todo items
-
-time.h:
-*   Probably some other funcs
-*   asctime_s
-*   ctime_s
-*   gmtime_s
-*   localtime_s
-
-wchar.h:
-*   Collation, IO, Tokenization, Conversions
+* In `cia-def.h` have macros defined depending on which modules were exported
+* Allow for ciabatta to be used by including headers
+* Define module requirements in `library.json`
 
+Support:
 
+* EssenseOS platform (?)
