Hello,

I'm running into some issues porting my icoextract package to 
pyproject.toml. I've gotten it to build and function with 
pybuild-plugin-pyproject, but it required some hacks along the way. 
However, I'm not sure if I'm seeing bugs/limitations in the toolchain, 
or I'm using the tools in some non-standard manner.

I've staged the changes at 
https://salsa.debian.org/jlu/icoextract/-/tree/debian/experimental?ref_type=heads. 
(Disclaimer: I am also the upstream author)

1) The .deb package seems to leave behind 
/usr/lib/python3/dist-packages/build/lib/icoextract. I can remove it 
manually with an execute_after_dh_auto_install rule, but it doesn't feel 
like this should be necessary. I've attached what the file list looks 
like without the rm -rf rule.

2) lintian complains about additional files in 
/usr/lib/python3.14/dist-packages/icoextract-0.3.0.dist-info/. The rest 
of the source files are installed to 
/usr/lib/python3/dist-packages/icoextract/, which is what I expect from 
previous versions currently in the archive.

3) `export PYBUILD_INSTALL_ARGS=--install-scripts=debian/tmp` doesn't 
seem to do anything now. I think that might be because --install-scripts 
is a setup.py specific feature, but the wiki is still hinting at this 
approach for packaging programs[1][2]. In my case, I'm fine with 
changing python3-icoextract to contain the library & CLI utils, and 
making icoextract a meta-package instead. AFAICT most distros did not 
bother to split the package at all.

I'd appreciate any advice on fixing up the port!

Best,
James
