DESCRIPTION

9       First a little history.  Virt-v2v has been through at least two
10       complete rewrites, so this is probably about the third version (but we
11       don't intend to rewrite it again).  The previous version was written in
12       Perl and can be found here:
13       https://git.fedorahosted.org/git/virt-v2v.git
14
15       The current version started out as almost a line-for-line rewrite of
16       the Perl code in OCaml + C, and it still has a fairly similar
17       structure.  Therefore if there are details of this code that you don't
18       understand (especially in the details of guest conversion), checking
19       the Perl code may help.
20
21       The files to start with when reading this code are:
22
23types.mli
24
25v2v.ml
26
27       types.mli defines all the structures used and passed around when
28       communicating between different bits of the program.  v2v.ml controls
29       how the program runs in stages.
30
31       After studying those files, you may want to branch out into the input
32       modules (input_*), the output modules (output_*) or the conversion
33       modules (convert_*).  The input and output modules define -i and -o
34       options (see the manual).  The conversion modules define what guest
35       types we can handle and the detailed steps involved in converting them.
36
37       Every other file in this directory is a support module / library of
38       some sort.  Some code is written in C, especially where we want to use
39       an external C library such as libxml2.
