tlbuild: Adding a new TeX-specific library module
6.6.3 Adding a new TeX-specific library module
----------------------------------------------
A TeX-specific library module in a subdirectory 'texk/LIB' may depend on
other TeX-specific libraries but must not depend on any generic library
from the TL tree. It is included in the same general ways as a generic
library (see the previous section), with these modifications:
* The library name 'LIB' is added to the M4 macro
'kpse_texlibs_pkgs', which is also in 'm4/kpse-pkgs.m4'.
* The fragment 'ac/withenable.ac' must use 'KPSE_WITH_TEXLIB'.
