Building the installer for Windows

Since the Caltech circulation desk staff are all running Windows-based computers, Hold It! currently only has configurations for creating installers for Windows. Here is the procedure to follow:

1. Run make ABOUT.html on a macOS or Linux system. This converts the README.md file into a self-contained ABOUT.html file with inlined graphics. It requires both pandoc and inliner, hence the need to run the command on a Mac or Linux system.
2. Next, build the Windows application normally.
3. Start up Inno Setup.
4. Open dist\installers\windows\holdit_innosetup_script.iss in Inno Setup.
5. Run the command Build ➜ Compile in Inno Setup.

The result of these steps should be an installer program left in the dist subdirectory.
