The code is divided into four main files (introduced here) and five support files (introduced in the next section). The file [[main.c]] will contain the driver for the whole program (see Section 2.2). «main.c*»= #include "global.h" @ The first pass over the source file is contained in [[pass1.c]]. It handles collection of all the file names, macros names, and scraps (see Section 2.3). «pass1.c*»= #include "global.h" @ The [[.tex]] file is created during a second pass over the source file. The file [[latex.c]] contains the code controlling the construction of the [[.tex]] file (see Section 2.4). «latex.c*»= #include "global.h" @
