[BioC] retrieve the gene symbols, full names etc given list of Entrez Gene IDs

[Luo Weijun]

Hello all,
Is there anyway to retrieve the gene symbols, full
names (discription), or other gene information, given
a list of Entrez Gene IDs (or the LocusLink) in
Bioconductor. Obviously, one way is to query Entrez
Gene web service ID by ID, but is there any way to get
connected to that web service from within
R/Bioconductor and retrieve the specific fields only(
like gene symbol, Name, Chromosome, MIM etc) of Entrez
Gene Records?
biomaRt seems to require interactive R, and mine is
command-line, and also it doesn't make one-on-one
mapping table since multiple ensemble IDs map to one
Entrez Gene ID, which is very annoying in making a
good-looking annotation table.
Thank you so much.
