.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \s-1POSIX\s0 module imports hundreds of symbols (functions and constants) by
default for backwards compatibility reasons. To avoid this, and to assist in
finding where functions have been imported from, specify the symbols you want
to import explicitly in the \f(CW\*(C`use\*(C'\fR statement. Alternatively, specify an empty
import list with \f(CW\*(C`use POSIX ()\*(C'\fR to avoid importing any symbols, and fully
qualify the functions or constants, such as \f(CW\*(C`POSIX::strftime\*(C'\fR.
