## Requirements

package require Tcl 8.4                         ; # Required runtime.
package require snit                            ; # OO system

# # ## ### ##### ######## ############# #####################
## Passes. The order in which the various passes are loaded is
##         important. It is the same order in which they will
##         register, and then be run in.

package require vc::fossil::import::cvs::pass::collar      ; # Coll'ect Ar'chives.
package require vc::fossil::import::cvs::pass::collrev     ; # Coll'ect Rev'isions.
package require vc::fossil::import::cvs::pass::collsym     ; # Coll'ate Sym'bols
package require vc::fossil::import::cvs::pass::filtersym   ; # Filter'  Sym'bols

# Note: cvs2svn's SortRevisionSummaryPass and SortSymbolSummaryPass
#       are not implemented by us. They are irrelevant due to our use
#       of a relational database proper for the persistent state,
#       allowing us to sort the data on the fly as we need it.

package require vc::fossil::import::cvs::pass::initcsets   ; # Init'ialize C'hange'Sets
package require vc::fossil::import::cvs::pass::breakrcycle ; # Break' R'evision Cycle's

# Note: cvs2svn's RevisionTopologicalSortPass is not a separate pass,
#       but was subsumed by the previous pass, by immediately saving
#       the order of consumed graph nodes to 'csorder'.
