+.Dt MANVM 1
+.Sh NAME
+.Nm manvm
+.Nd format and display the on-line Java VM manual pages
+.Sh SYNOPSIS
+.Nm
+.Op Ar name
+.Sh DESCRIPTION
+.Nm Manvm
+provides a convenient system for displaying the on-line manual pages
+for different Java VMs without having to add their (conflicting) manual
+page directories to
+.Ev MANPATH
+.Pp
+By default,
+.Nm
+will select the most
+.Dq native
+and up to date version of the Java VM when locating the manual page to
+be displayed.
+This selection process is akin to that used by
+.Nm javavm
+in that the same environment variables and processes are used.
+.Pp
+The manual pages are displayed using
+.Nm man ,
+and all applicable environment variables, save for
+.Ev MANPATH ,
+are respected.
+Options may be passed to
+.Nm man
+using the
+.Ev JAVAVM_OPTS
+environment variable and its associated sub-variables and configuration
+file.
+.Sh ENVIRONMENT
+.Bl -tag -width indent
+.It Ev JAVA_HOME
+The presence of this variable in the environment when executing
+.Nm
+will override all other considerations regarding the Java VM whose on-line
+manual pages will be displayed and the manual pages located at
+.Pa ${JAVA_HOME}/man
+will be used.
+.Pp
+.It Ev JAVA_OS
+A space delimited list of operating systems.
+The on-line manual pages to be displayed must come from a Java VM that has
+been created for one of the operating systems in the list.
+.Pp
+Currently allowed operating system values are
+.Ql native
+and
+.Ql linux .
+.It Ev JAVA_VENDOR
+A space delimited list of Java VM vendors.
+The on-line manual pages to be displayed must come from a Java VM that has
+been released by one of the vendors in the list.
+.Pp
+Currently allowed vendors are
+.Ql bsdjava ,
+.Ql freebsd ,
+.Ql blackdown ,
+.Ql ibm
+and
+.Ql sun .
+.It Ev JAVA_VERSION
+A space delimited list of versions of the Java VM from which the on-line
+manual pages may come.
+By appending a
+.Ql +
+to a version, the on-line manual pages from any Java VM with a version
+greater than or equal to the given version will be used.
+.Pp
+Currently allowed versions are
+.Ql 1.1 ,
+.Ql 1.1+ ,
+.Ql 1.2 ,
+.Ql 1.2+ ,
+.Ql 1.3 ,
+.Ql 1.3+ ,
+.Ql 1.4 ,
+.Ql 1.4+ ,
+.Ql 1.5
+and
+.Ql 1.5+ .
+.It Ev JAVAVM_OPTS
+The contents of this environment variable will be passed to the invoked
+.Nm man
+as options.
+For more information on environment variables which can be used to set
+options see
+.Pa %%PREFIX%%/etc/javavm_opts.conf.dist .
+.El
+.Sh EXAMPLES
+.Bl -tag -width indent
+.It Pa %%LOCALBASE%%/bin/manvm java
+Display the on-line manual page for the
+.Nm java

+.Dq native
+Java VM registered with
+.Nm javavm .
+.It Ev JAVA_VERSION=1.5 Pa %%LOCALBASE%%/bin/manvm javac
+Display the on-line manual page for the
+.Nm javac
+programme for a Java VM which is version 1.5.
