You're getting the SIGSEGV because cs2ecma.exe (invoked by the mdcs2ecma
script) was compiled against the .NET 1.0 profile, not the .NET 2.0
profile.  Since your code uses .NET 2.0 types -- in this case
System.Collections.Generic.Dictionary -- the type can't be loaded by
mdcs2ecma.  This probably shouldn't cause a SIGSEGV, but even if it
didn't, you'd probably get a TypeLoadException or something else

The solution is to avoid mdcs2ecma.  Use `monodocer' instead, as it can
properly handle .NET 2.0 assemblies:

	monodocer -pretty -assembly:Metashell.Core.dll \

The above command creates ECMA-style documentation within the directory

You can then use mdassembler to create .zip files which can be used by
the `monodoc' browser:

	mdassembler --ecma Metashell.Core/en -o MetashellCore-docs

which creates the files MetashellCore-docs.tree and
MetashellCore-docs.zip.  Then create a MetashellCore-docs.source file
with the contents:

        <?xml version="1.0"?>
          <source provider="ecma" basefile="MetashellCore-docs" path="classlib-mono"/>

Copy MetashellCore-docs.source, MetashellCore-docs.tree, and
MetashellCore-docs.zip into `monodoc --get-sourcesdir`, and they should
then be usable by monodoc.
