ProcrastiBlog

Be warned: there is a @Comment directive in BibTeX, but it doesn't appear to do anything.

UPDATE: @Comment works as expected so long as you use it outside any other directive. E.g., the following will not work,

@InProceedings{ key,
  title = {\BibTeX comments considered harmful},
  author = {Christopher L. Conway},
  booktitle = {Procrastiblog Symposium on \LaTeX Arcana},
  year = 2007,
  @Comment{ This never actually happened. }
}

whereas the following is fine,

@InProceedings{ key,
  title = {\BibTeX comments considered harmful},
  author = {Christopher L. Conway},
  booktitle = {Procrastiblog Symposium on \LaTeX Arcana},
  year = 2007,
}

@Comment{ The above never actually happened. }
