LGTM! But I think the build script should be placed in the project root directory.

@LuminolT, do you have any comments? If not, I will proceed with the Squash merge.

Thanks @jamesnulliu for your contribution.

@Errant404, I have reviewed the PR. It works on my local environment (Endeavor OS).

However, I still have a few concerns:

First, I noticed that the Makefile and shuthesis.dtx files are removed. These are part of the process that generates the shuthesis.pdf documentation. Although we might not actively use it anymore, they might still need to be preserved (or archived).

Second, some half-width characters were replaced with full-width ones, e.g. . -> 。 and , -> ，. This could be related to the thesis writing guidelines. I'm not sure whether certain departments (especially the Mathematics Department) have specific requirements regarding the use of half-width characters.

These issues need further discussion, so please refrain from merging for now.

I have further reviewed the related issues.

Regarding the first problem, although this modification approach will increase the difficulty of subsequent low-level configurations, overall, it will work, and there are no issues.

As for the second one, based on the GB/T 7713.1-2006 national standard, changing to full-width characters is perfectly acceptable.

@Errant404 please go ahead and merge this PR if there are no further issues. THX!
