"""
This script translates messages from a .pot file to Spanish using the
GoogleTranslator from the deep_translator library.

Steps:
1. Read the content of a .pot file which contains msgid entries.
2. Use regular expressions to extract all msgid entries.
3. Translate each msgid entry from English to Spanish.
4. Write the translations into a new .po file with the appropriate formatting.

Dependencies:
- deep_translator: A Python library that provides a simple interface to various
 translation services, including Google Translate.
- re: The built-in Python module for regular expressions, used to find msgid
entries in the .pot file.
