+\begin_layout Description
+Notes: The
+\family sans
+bm
+\family default
+ package defines commands to access bold math symbols.
+ The basic command is
+\family typewriter
+
+\backslash
+bm
+\family default
+ which makes its argument bold.
+ The argument may be any math object from a single symbol to an expression.
+ If available, ultra bold fonts can be accesed through the
+\family typewriter
+
+\backslash
+hm
+\family default
+ command (aliased to
+\family typewriter
+
+\backslash
+heavysymbol
+\family default
+).
+ The
+\family typewriter
+
+\backslash
+bm
+\family default
+ command is similar to the
+\family sans
+amsmath
+\family typewriter
+
+\backslash
+boldsymbol
+\family default
+ command, but the
+\family sans
+bm
+\family default
+ version is rather more careful in the way it does things.
+ Be aware that this package allocates symbol fonts for bold fonts into the
+ normal math version, such that, when using other packages that allocate
+ many symbol fonts, they can be exhausted.
+ In this case, one can make do with the
+\family typewriter
+
+\backslash
+boldsymbol
+\family default
+ command.
