# After that PR was merged, and the recipes were submitted to [conda-forge/staged-recipes](https://github.com/conda-forge/staged-recipes) Linux, OSX, or Windows user would just have to:
# 
# ```bash
# conda install -c conda-forge latex2sympy
# ```

# While a developer on any of those platforms could choose to use:
# 
# ```bash
# conda install -c conda-forge antlr4
# ```
