The bundle provides three packages: The mhchem package provides commands for typesetting chemical molecular formulae and equations. The hpstatement package provides commands for the official hazard statements and precautionary statements (H and P statements) that are used to label chemicals. The rsphrase package provides commands for the official Risk and Safety (R and S) Phrases that are used to label chemicals.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
