+    (description
+     "ASEB is an R package to predict lysine sites that can be acetylated by a
+specific @dfn{KAT} (K-acetyl-transferases) family.  Lysine acetylation is a
+well-studied posttranslational modification on kinds of proteins.  About four
+thousand lysine acetylation sites and over 20 lysine KATs have been
+identified.  However, which KAT is responsible for a given protein or lysine
+site acetylation is mostly unknown.  In this package, we use a
+@dfn{GSEA}-like (Gene Set Enrichment Analysis) method to make predictions.
+GSEA method was developed and successfully used to detect coordinated
+expression changes and find the putative functions of the long non-coding
+RNAs.")
