The package deals with the behaviour of the LaTeX internal command \@ifnextchar, which skips blank spaces. This has the potential to surprise users, since it can produce really unwanted effects. A common example occurs with brackets starting a line following \\: the command looks for an optional argument, whereas the user wants the brackets to be printed. The package offers commands and options for modifying this behaviour, maybe limited to certain parts of the document source.
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.
