# numpy-py3/cfg - "Build" settings for package

#---------------------------------------------------------------------

[technotes]

1. The source tarball used by this  package was created based on "git"
upstream sources. The following command was used:

      ocgitfetch --run \
--checkout=v2.4.6 \
--deletegit \
https://github.com/numpy/numpy.git

#---------------------------------------------------------------------

2. It's  difficult to build this package without permitting online ac-
cess. So, the build procedure is fragile and updates are highly likely
to break it.

#---------------------------------------------------------------------

3. Updates to  this  package may  necessitate  updates to  one or more
Python3  packages.  In  this event, it may or  may not be necessary to
explicitly uninstall one or more of the  Python3 packages in  question
before updating them.

In Spring 2026,  this proved to be an issue for "trove-classifiers" in
particular.
