Without further ado, the following was found: Issue: shopuld → should "Ideally, a library for the C language is designed such that each header file " "presents the interface to a coherent software module. It provides a small " "number of function declarations and exposes only data types and constants " "that are required for use of those functions. Together, these are termed an " "API or I<application program interface>. Types and constants to be shared " "among multiple APIs shopuld be placed in header files that declare no " "functions. This organization permits a C library module to be documented " "concisely with one header file per manual page. Such an approach improves " "the readability and accessibility of library documentation, and thereby the " "usability of the software."
