	tprofilesearch is an EGCG programme that will do that.
Make sure that EGCG is installed en your machine. Make sure
also that tprofilesearch was compiled with definitions to
scan the whole ESTs (memory limitrations) (contact your GCG manager...).

	It depends of how it was configured on your system. A general
answer is to make a FOSN with database names. This look like :

	Get the names of available databases with gcgver.
Then you can use profilesearch against @my_list_of_DB.

	Phylip is not a programme, it's a complete package dedicated
to phylogenetic analysis. Remember that this is a complete field
of molecular biology and that using the phylip package (so, doing
good phylogenetic analysis) need some knowledge.

	For GCG8, Frd compiles an HTML version of the doc. New GCG
licence make it available only for sites where GCG has a valid licence.
(you can contact Fred at : plewniak at igbmc.u-strasbg.fr). GCG9 comes
with its own HTML documentation.
