OPSIN (Open Parser for Systematic IUPAC Nomenclature) is a freely
available, open-source Java library designed to accurately interpret
systematic IUPAC chemical nomenclature and convert it into chemical
structures. It offers high precision and recall for organic chemical
names, including complex heterocycles and stereochemistry.
OPSIN supports multiple output formats such as SMILES, InChI, and CML,
and can also generate PNG, SVG, and JSON. It can be deployed as a web
service, a local command-line application for bulk conversion, or
integrated into other systems via third-party Python libraries. Its
extensible design and robust parsing mechanism make it a valuable tool
for chemical information extraction from scientific literature and
patents, research and development, and populating chemical databases.
some Maven build ports: pass JAVA_HOME to maven
When a port defines JAVA_VERSION but during the build multiple
jdk versions are installed, Maven does not always use the defined
version if JAVA_HOME is not set in the environment.

Mk/**java.mk: Convert bsd.java.mk to USES
The following features have been added or changed:
- Instead of USE_JAVA use USES=java. This defaults to
USES=java:build,run if NO_BUILD is undefined. Else it defaults to
USES=java:run
- Instead of USE_ANT=yes use USES=java:ant which also implies
USES=java:build
- Instead of JAVA_BUILD=yes use USES=java:build. Does not imply run or
extract
- Instead of JAVA_EXTRACT=yes use USES=java:extract does not imply
build or run
- Instead of JAVA_RUN=yes use USES=java:run does not imply extract or
build
- Instead of USE_JAVA=<version> use USES=java and JAVA_VERSION=<version>

*/*: properly depend on Maven package
devel/maven and devel/maven39 do not provide mvn(1) from LOCALBASE that
one comes from devel/maven-wrapper instead. Therefore, one should depend
on the package rather than a non-existing executable/script.

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
