Most of the files contain decoders for specific syscalls (like mount.c, statx.c,
getcpu.c, and so on) or groups of syscalls (like mem.c, signal.c,
fanotify.c, ...).
There are several files that contain generic strace code (strace.c,
util.c, defs.h,
syscall.c) and some auxiliary files with helper functions (like
ucopy.c or xmalloc.c).
The pretty common autotools-related stuff is here as well (like configure.ac,
m4 directory, and so on). The xlat directory contains files with related named
constants decriptions; they are processed to headers with gen.sh
script. The tests
directory contains tests. The maint directory is a palce for
maintenance scripts used
for the distribution preparation process. The linux directory contains
various headers
with definitions specific to architectures (like arch_get_scno for
obtaining syscall
number, or syscallent with table of syscall descriptions). If you have
any further specific questions,
don't hesitatte to ask.

The strace.c file contains main routine.
