#W  atlasrep.tst         GAP 4 package AtlasRep                 Thomas Breuer
##
##  This file contains among others the function calls needed to perform some
##  of the sanity checks mentioned in the corresponding manual section.
##
##  In order to run the tests, one starts GAP from the 'tst' subdirectory
##  of the 'pkg/atlasrep' directory, and calls 'Test( "atlasrep.tst" );'.
##
##  If one of the functions 'AGR.Test.Words', 'AGR.Test.FileHeaders' reports
##  an error then detailed information can be obtained by increasing the
##  info level of 'InfoAtlasRep' to at least 1 and then running the tests
##  again.
