=head1 NAME

FCM::Context::Make

=head1 SYNOPSIS

    use FCM::Context::Make;
    my $ctx = FCM::Context::Make->new();

=head1 DESCRIPTION

Provides a context object for the FCM make system. It is a sub-class of
L<FCM::Class::HASH|FCM::Class::HASH>.

=head1 OBJECTS

=head2 FCM::Context::Make

An instance of this class represents a make. It has the following
attributes:

=over 4

=item ctx_of

A HASH containing the (keys) IDs and the (values) context objects of the make.

=item description

A description string for this make.

=item dest

The destination of this make.

=item dest_lock

The destination lock of this make.

=item error

This should be set to the value of the exception, if this make ends in one.

=item inherit_ctx_list

An ARRAY of contexts inherited by this make.

=item name

The name of the context. This is useful if we need to have multiple (but
non-overlapping) "fcm make" runs in the same destination. (Default is a null
string.)

=item option_of

A HASH to store the options of this make. See L</OPTION> for detail.

=item status

The status of the make.

=item steps

The names of the steps to make.

=back

=head1 OPTION

The C<option_of> attribute of a FCM::Context::Make object may contain the
following elements:

=over 4

=item config-file

An ARRAY of configuration file names.

=item directory

The working directory of the make.

=item ignore-lock

Ignores lock file in the destination.

=item jobs

The number of (child) threads that can be run simultaneously.

=item new

Performs a make in "new" mode (as opposed to the "incremental" mode).

=back

=head1 CONSTANTS

=over 4

=item FCM::Context::Make->ST_UNKNOWN

The status of a make context or the context of a subsystem. Status is unknown.

=item FCM::Context::Make->ST_INIT

The status of a make context or the context of a subsystem. The make or the
subsystem has initialised, but not completed.

=item FCM::Context::Make->ST_OK

The status of a make context or the context of a subsystem. The make or the
subsystem has completed successfully.

=item FCM::Context::Make->ST_FAILED

The status of a make context or the context of a subsystem. The make or the
subsystem has failed.
