There are small typos in: - tutorials/installing_scientific_packages.md - tutorials/sqlite3_howto/README.md - tutorials/sqlite3_howto/code/update_or_insert_records.py - useful_scripts/conc_gzip_files.py Fixes: - Should read `existing` rather than `exisiting`. - Should read `conveniently` rather than `conviniently`. - Should read `calculate` rather than `calulate`. - Should read `accommodate` rather than `accomodate`.
