-------------------------------------------------------------------------------
--  Lingenic-Text
--  Formally Verified Unicode Text Processing Library
--
--  C library project: builds the proved SPARK core plus the C binding
--  (src-c/lingenic_text_c.ads/.adb) as a standalone static library.
--
--  Usage from C:
--    1. call lingenic_text_cinit()  (elaboration, generated by gprbuild)
--    2. call lt_init("<ucd dir>")
--    3. use the lt_* API (see include/lingenic_text.h)
--
--  Build:
--    gprbuild -P lingenic_text_c.gpr -j0
--
--  Output:
--    lib-c/liblingenic_text_c.a
