readdir - Required for glob
package - Package management with the package command
load - Load binary extensions at runtime with load or package
posix - Posix APIs including os.fork, os.wait, pid
regexp - Tcl-compatible regexp, regsub commands
signal - Signal handling
stdlib - Built-in commands including lassign, lambda, alias
syslog - System logging with syslog
tclcompat - Tcl compatible read, gets, puts, parray, case, ...
