Manpages' synopses are confusing

Hello,
First and foremost thank you for your work.

Using Ubuntu latest LTS and uutils 0.10.0, the Synopsis section of the manpages have been altered in a fashion where it is impossible to understand the basic way to invoke a command with resorting to tldr examples.
For example, seq shows the following:

$ man seq

SYNOPSIS
       seq [-s|--separator] [-t|--terminator] [-w|--equal-width] [-f|--format] [-h|--help] [-V|--version] [numbers]

and nowhere is it described what [numbers] consist of. There's no way to know how to properly invoke the command.

The old version used to show the different way of invoking:

SYNOPSIS
       seq [OPTION]... LAST
       seq [OPTION]... FIRST LAST
       seq [OPTION]... FIRST INCREMENT LAST

Same thing for install and many other commands which have various ways of being invoked.
If I may remark: most commands have several lines of options when listed inline, and listing them in the synopsis seem particularly suboptimal when it deters basic understanding of the command.

Start by locating how the Rust project generates the manpage synopsis for commands such as seq and install. Compare the current synopsis with the older multi-form examples, then identify how similar commands represent multiple invocation forms. Done means the manpages explain each supported invocation clearly, including what seq’s numeric arguments mean.
