# Disclaimer: this script has been done as a quick n' dirty way to convert
|
||
# markdown to Planète Casio's BBcode. As it, it does support only those
|
||
# features:
|
||
# - # H1 title
|
||
# - ## H2 title
|
||
# - ### H3 title
|
||
# - *emphasis text*
|
||
# - **strong text**
|
||
# - [link](https://domain.tld)
|
||
# - {{ tableofcontents }}
|
||
#
|
||
# More features may be added in the future, but this script is provided as it.
