# @summary
# Installs and configures `mod_event`.
#
# @param startservers
# Sets the number of child server processes created at startup, via the module's `StartServers` directive. Setting this to `false`
# removes the parameter.
#
# @param maxrequestworkers
# Sets the maximum number of connections Apache can simultaneously process, via the module's `MaxRequestWorkers` directive. Setting
# these to `false` removes the parameters.
#
# @param minsparethreads
# Sets the minimum number of idle threads, via the `MinSpareThreads` directive. Setting this to `false` removes the parameters.
#
# @param maxsparethreads
# Sets the maximum number of idle threads, via the `MaxSpareThreads` directive. Setting this to `false` removes the parameters.
#
# @param threadsperchild
# Number of threads created by each child process.
#
# @param maxconnectionsperchild
# Limit on the number of connections that an individual child server will handle during its life.
#
# @param serverlimit
# Limits the configurable number of processes via the `ServerLimit` directive. Setting this to `false` removes the parameter.
#
# @param threadlimit
# Limits the number of event threads via the module's `ThreadLimit` directive. Setting this to `false` removes the parameter.
#
# @param listenbacklog
# Sets the maximum length of the pending connections queue via the module's `ListenBackLog` directive. Setting this to `false` removes
# the parameter.
