5// The file contains the implementation of the mini_installer re-versioner.
6// The main function (GenerateNextVersion) does the following in a temp dir:
7// - Extracts and unpacks setup.exe and the Chrome-bin folder from
8//   mini_installer.exe.
9// - Inspects setup.exe to determine the current version.
10// - Runs through all .dll and .exe files:
11//   - Replacing all occurrences of the Unicode version string in the files'
12//     resources with the updated string.
13//   - For all resources in which the string substitution is made, the binary
14//     form of the version is also replaced.
15// - Re-packs setup.exe and Chrome-bin.
16// - Inserts them into the target mini_installer.exe.
17//
18// This code assumes that the host program 1) initializes the process-wide
19// CommandLine instance, and 2) resides in the output directory of a build
20// tree.  When #2 is not the case, the --7za_path command-line switch may be
21// used to provide the (relative or absolute) path to the directory containing
22// 7za.exe.
