# NAME
# postinstall.subr -- post-installation actions for packages
#
# SYNOPSIS
# task_postinstall <datafile>
#
# DESCRIPTION
# The task_postinstall function performs actions that SHOULD occur
# AFTER the package files are installed into their final location
# for the installation:
#
# o Copy configuration files into correct locations.
# o Set special permissions on package files and directories.
# o Rebuild the system run-time library search path database.
# o Update fonts databases.
# o Create caches within GTK+ icon theme directories.
# o Register shells in the system shells database.
# o Register GNU info files.
# o Update OCaml module run-time library search path database.
#
# The datafile contains lines of the form:
#
# # <keyword>: <arg> ...
#
# These lines are used as input to the various script functions.
#
# RETURN VALUES
# Returns 0 on success, and >0 if an error occurs.
#
# ENVIRONMENT
# The following variables are used if they are set:
#
# TASK_VERBOSE
# List of package tasks that should emit verbose output.
# If ${TASK_VERBOSE} is "all", then all tasks are verbose.
# If ${TASK_VERBOSE} is "none", then no tasks are verbose.
# Otherwise, if one of the tasks is "default", then the
# default list of tasks are verbose.
