Description

Use build-message when you have a multistep build and want to be able to quickly identify the current build step or some other important information in long logs. The message that you log using build-message is formatted with a 4 character prefix spacing and a dashed line 8 characters longer than the message. Like this:

If the message is really long, the terminal width will be the max width, or 80 characters if the terminal width isn't discoverable. The build message will be split (if possible on spaces) at a relevant position. If possible build-message tries to insert 4 spaces before the text, but will accomodate to the available space.

Example with 16 character width terminal:
